Top best answers to the question «Can electric field lines end without charge being present»

  • No, if there is a single positive charge, then field lines originate from it and tend towards the infinity . They never end. However, if we have positive and negative charges, then lines of force terminate at a negative charge.

FAQ

Those who are looking for an answer to the question «Can electric field lines end without charge being present?» often ask the following questions:

👉 Electric field lines when one charge greater?

Following are the rules for drawing electric field lines: The field line begins at the charge and ends either at the charge or at infinity. When the field is stronger, the field lines are closer to each other. The number of field lines depends on the charge. The field lines should never crossover. Electric field and electric field line are tangent at the point where they pass through.

👉 How are electric field lines related to charge?

  • Given a point charge, or a particle of infinitesimal size that contains a certain charge, electric field lines emanate radially in all directions. If the charge is positive, field lines point radially away from it; if the charge is negative, field lines point radially towards it.

👉 Are electric field lines perpendicular to field lines?

Since the electric field lines point radially away from the charge, they are perpendicular to the equipotential lines. The potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines. Click to see full answer.

Close-up, an arbitrary arrangement of charges can have an electric field of great detail that isn't easily visualized without a computer. However, as the scale increases, these local variations will drop off quickly, and at great distances the field will tend to look like E ( x ) = k ∑ i q i ( r i − x ) 2 ≈ k Q net ( r ˉ − x ) 2 . \displaystyle E(x) = k \sum_i\frac{q_i}{(r_i-x)^2} \approx k\frac{Q_\text{net}}{(\bar{r}-x)^2}.

Electric field lines point away from positive charges (like charges repel) and towards negative charges (unlike charges attract). Field lines are drawn closer together where the field is stronger. Field lines do not touch or cross each other. Field lines are drawn perpendicular to a charge or charged surface.

Make sure you represent both the magnitude and direction of the electric field adequately. Note that the number of lines into or out of charges is proportional to the charges. (a) Draw the electric field lines map for two charges and situated 5 cm from each other. (b) Draw the electric field lines map for two charges and situated 5 cm from each ...

Electric field can be considered as an electric property associated with each point in the space where a charge is present in any form. An electric field is also described as the electric force per unit charge. The formula of electric field is given as; E = F /Q. Where, E is the electric field. F is a force. Q is the charge. Electric fields are usually caused by varying magnetic fields or electric charges. Electric field strength is measured in the SI unit volt per meter (V/m).

Do electric field lines exist?

Electric Fields: do exist Field Lines: do not exist They provide a potential difference, a voltage

Do electric field lines terminate?

Electric field lines either originate on positive charges or come in from infinity, and either terminate on negative charges or extend out to infinity.

Who discovered electric field lines?

Who was the discoverer of magnetic field lines?

  • . Magnetic field lines were introduced by Michael Faraday (1791-1867) who named them "lines of force." Faraday was one of the great discoverers in electricity and magnetism, responsible for the principles by which electric generators and transformers work, as well as for the foundations of electrochemistry.
Which is type of field is present near a moving electric charge?

Which type of field is present near a moving electric charge? magnetic field. Can a stationary charge experiences a magnetic force? For a stationary …

How are energy lines like electric field lines?
  • Energy can flow like traffic, some leaving to the right as a possibly equal amount comes in from the right, so there are like electric field lines in that energy flow field lines starts or stop is where energy density is changing (either changing to electromagnetic energy or changing from electromagnetic energy).
What are electric field lines and equipotential lines?

perpendicularto the field lines. In other words, for a electric field, the equipotential surfaces are allel planes at right angles to the direction of electric field. -7:Electric field lines and equipotential surfaces for a point charge. The equipotential surfaces around a point charge are spheres.

In which case is electric field present?

Electric field are present when there are electric forces. Electric force can be created when there is a potential difference in the charges of the particles. Cases like rubbing two objects creates static force thus creating electric field. This can be manifested when you rub two balloons or when you comb your hair.

How are electric field lines and equipotential lines alike?
  • Electric field lines begin on positive charges and radiate away from them toward negative charges, where they terminate. Equipotential lines are lines connecting points of the same electric potential. All electric field lines cross all equipotential lines perpendicularly.
Why are equipotential lines perpendicular to electric field lines?

Yes. The electric field (for the electrostatic case, which I presume you imply) is the gradient of the potential field. Then the math gives it to you. The gradient of a function is always perpendicular to the constant contours of a function. If th...

Are electric field lines a reality?

No, they do not exist. Electric field lines are only imaginary. They are the paths along which an imaginary unit charge would move when free. Their number is infinite as paths (Electric field lines) can be infinite.

Are electric field lines closed curves?

Magnetic field lines are closed curves but electric field lines are not.

Are electric field lines ever broken?

The electric field-lines associated with a positive point charge are a set of unbroken, evenly spaced (in solid angle) straight-lines which radiate from the charge--see Fig. 9.Thus, the tangent to the field-lines is always directed radially away from the charge, giving the correct direction for the electric field.

Can electric field lines be broken?

(i) An electrostatic field line is a continuous curve. That is, a field line cannot have sudden breaks.

Can two electric field lines intersect?
  • No. Two electric field lines can not intersect because tangent at any point on electric field line gives the direction of electric field. If two electric field lines intersects then at the point of intersection two tangent is possible which means there are two direction of electric field at the point of intersection which is not possible.
Do electric field lines ever end?

For instance the electric field induced by a time-varying magnetic field is not conservative, and thus its field lines can form closed loops. Such fields would also arise in circuits. Electric field lines may also not end anywhere if there are no sources whatsoever.

Do magnetic and electric field lines?

Monopoles do not exist. This is because magnetic field lines start from the north pole and end at the south pole. Therefore, magnetic fields have both poles i.e. dipoles only. 6. Electric field and magnetic field are perpendicular to

Electric field lines are material objects?

1) Electric field lines represent the paths of particles. 2) The electric field is quantized and exists only in certain parts of space. 3) The relative magnitude of the electric field is proportional to the density of the field lines. 4) Electric field lines are material objects.

Electric field lines mean what physics?

Electric Field Lines can be easily defined as a curve which shows the direction of an electric field when we draw a tangent at its point. The concept of electric field was first proposed by Michael Faraday, in the 19 th century. Faraday always thought of electric field lines as ones which can be used to describe and interpret the invisible electric field.

How are electric field lines drawn?

The rules for drawing electric field lines for any static configuration of charges are The lines begin on positive charges and terminate on negative charges. The number of lines drawn emerging from or terminating on a charge is proportional to the magnitude of the charge. No two field-lines ever cross in a charge-free region.

What do electric field lines indicate?
  • An electric field can be visualized by drawing field lines, which indicate both the magnitude and direction of the field. Field lines start on positive charges and end on negative charges.
Why are electric field lines curved?

Why are electric field lines curves?

Yes, the electrostatic field line is a continuous curve because a unit charge always experiences a continuous force when it is placed in an electrostatic field. The unit charge is the charge that passes through the cross-section of an electric conductor that carries one ampere of current in one second.

Why are electric field lines perpendicular?

Why are electric field lines radial?

Electric field is the force experienced by unit positive charge. Electric field lines is a diagram which shows you where the force acts when an unit positive charge is kept at that point. When a unit positive charge is kept near a +ve charge, it experiences a repulsive force (outward) hence lines are radially outward.
