Top best answers to the question «Under which condition electric intensity at a point is zero but electric potential is not zero»

So there is the answer. The electric potential at the midpoint between the two +Q charges where the electric field is zero is nonzero and negative. The minus sign says that you have to do work to bring the positive test charge to the zero field point from infinity.

If we have a positive and a negative charge of equal magnitude separated by a certain distance , then the electric potential at the mid point of the path is 0 but the electric field intensity is non zero there.

FAQ

Those who are looking for an answer to the question «Under which condition electric intensity at a point is zero but electric potential is not zero?» often ask the following questions:

👉 Is the electric potential of a point zero?

  • A point P at the exact half way of two opposite charge will have zero potential (assume potential is set zero at infinity) ,but the electric field will not be zero at point P. How to completely explain this? You are correct.

👉 When is the electric potential at a point zero?

  • At a point midway between two equal and opposite charges, the electric potential is zero but the electric field is not zero. The electric potential at a point is said to be one volt if one joule of work is done in moving one Coloumb of the charge against the electric field.

👉 Can electric potential zero?

Yes, electric potential can be zero at a point even when the electric field is not zero at that point… At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.

Can electric potential at a point with zero but not the electric field give example?

Yes, it is possible. Example : 1. Inside uncharged spherical shell and charged conductor electric field is zero but electric potential cannot zero.

Can electric potential exists at a point in a region where electric field is zero?

(a) No, just because the electric field is zero at a particular point, it does not necessarily mean that the electric potential is zero at that point… At the midpoint between the charges, the electric field due to the charges is zero, but the electric potential due to the charges at that same point is non-zero.

Why is electric field zero at a point of zero?
  • Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite.
Find where the electric potential is zero?
  • If you place the -1 C charge 1 cm away from the point then the potential will be zero there. There are two places along the line that will work: 1 cm to the left of the point and 1 cm to the right of the point. (You should verify this using the simulation.)
When is electric field and potential zero?

Yes. The electric field might be generated for example by two charges: +5C and −4C separated by 2 meters. There is a point in between them where the potential is 0 (the electric potential is also 0 in the infinite) but in that point the electric field vector is not null.

Why is electric potential zero opposite charges?

Since the charges have equal magnitude and the distance from each to the mid point is the same, the magnitude of the potential energy contributed by each charge is the same, but the signs are opposite, so the net potential energy should be zero.

At which point or points is the electric field zero in?

The Attempt at a Solution. I originally thought that the electric field past point 7 (i.e. points 8,9, 10) was the solution. However, this is wrong. I then considered point 1, yet that was wrong too. I even considered that there was no point at which the electric field is zero.

What point is the electric field zero?

There is a spot along the line connecting the charges, just to the "far" side of the positive charge (on the side away from the negative charge) where the electric field is zero. In general, the zero field point for opposite sign charges will be on the "outside" of the smaller magnitude charge.

When is the electric field intensity zero in a conductor?
  • 3 Answers. If the charges in a conductor in equilibrium at rest, the electric field intensity in all interior points of the same must be zero, otherwise, would move the loads caused an electric current. Within a conductor arbitrarily draw a closed surface , and it follows that: The electric field is zero, on all points of said surface.
Is the electric potential of the earth zero?
  • Earth has an electric field but it doesn't have any potential.If it would any currents would have been produced. The electric field in terms of the potential is E → = − ∇ V = − ∂ V ∂ x x ^ − ∂ V ∂ y y ^ − ∂ V ∂ z z ^.
When is work zero in electric potential energy?
  • Important Points At a point midway between two equal and opposite charges, the electric potential is zero but the electric field is not zero. The electric potential at a point is said to be one volt if one joule of work is done in moving one Coloumb of the charge against the electric field.
Where is the electric potential equal to zero?

Where is the electric potential (with respect to infinity) equal to zero? Yes, the electric field is a vector and the electric potential is a scalar — so you would think that the question about...

At what point is the electric field zero?

There is a spot along the line connecting the charges, just to the "far" side of the positive charge (on the side away from the negative charge) where the electric field is zero. In general, the zero field point for opposite sign charges will be on the "outside" of the smaller magnitude charge.

Can electric potential at a point be negative?

Electric potential is a property of the field itself, so, if the charge is negative, the electric potential of a test charge is negative at any point besides when the test charge is infinitely far away, in which case it would be zero.

What is the electric potential at a point?
  • The electric potential at a point in an electric field is defined as the amount of work done in moving a unit positive charge from infinity to that point along any path when the electrostatic forces are applied. Suppose that a positive charge is placed at a point.
What is the reference point of electric potential?
  • Written By: Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. Typically, the reference point is Earth, although any point beyond the influence of the electric field charge can be used.
What is the electric potential at a point due to point charge?
  • Electric Potential Due to Point Charge The electric potential at a point in an electric field is characterized as the measure of work done in moving a unit positive charge from infinity to that point along any path when the electrostatic powers/forces are applied. Assume that a positive charge is set at a point.
What does it mean if electric potential is zero?

What zero potential means, roughly, is that the charges in your system have cancelled out. For example exactly half way (or otherwise equidistant from them) between two equal and oppositely charged point charges, potential is zero.

Why is the electric potential of the earth zero?
  • In the standard solution the electric potential of the outer shell is taken to be zero saying that since it is earthed and potential of the earth is zero so electric potential at the surface of the outer shell must also be zero. Then the potential due to the charges on the surfaces...
Why is the electric field zero at this point?

Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite. That point is halfway between two like charges.

Is it possible to have a point where potential is zero but not electric field give two examples?

Yes take an example. If we have a positive and a negative charge of equal magnitude separated by a certain distance , then the electric potential at the mid point of the path is 0 but the electric field intensity is non zero there.

Which quantity is electric potential?

Electric potential is the electric potential energy per unit charge. In equation form, V=U/q, where U is the potential energy, q is the charge, and V is the electric potential. Since both the potential energy and charge are scalar quantities, so does the potential.

In which orientation is potential energy of an electric dipole zero in a uniform electric field?

When an dipole is placed in a uniform electric field with a angle of 90° or π/2, its potential energy is 0.

Can a point lie at the same electric potential?
  • (93) that the points and lie at the same electric potential (i.e., ). The locus of all the points in the vicinity of point which lie at the same potential as is a plane perpendicular to the direction of the local electric field.
Can an electric potential exist at a point in?

3 Answers. Yes. The electric field might be generated for example by two charges: +5C and −4C separated by 2 meters. There is a point in between them where the potential is 0 (the electric potential is also 0 in the infinite) but in that point the electric field vector is not null.
