## Top best answers to the question Â«How to relate electric field and chargeÂ»

The strength of an electric field as created by source charge Q is **inversely related to square of the distance from the source**. This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases.

Charge density is not enough to have an electric field. You also need the distance from your charge. For point charges, electric field is [tex] E = k \frac{Q} {d^2} [/tex] where k is Coulomb's constant, Q is charge, and d is distance. If you have another charge q at distance d, the force between charges will be F = q*E, that's where E = F/q comes from.

Relation of Electric Field to Charge Density. Since electric charge is the source of electric field, the electric field at any point in space can be mathematically related to the charges present. The simplest example is that of an isolated point charge. For multiple point charges, a vector sum of point

Electric field is defined as the electric forceper unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. The electric field is radially outward from a positive charge and radially in toward a negative point charge.

according to steinmetz, this is how the magnetic field is related geometrically to the electric field. the radial lines are the electric field while the concentric circles are the magnetic field. in its center is the electric charge. the electric field lines are the FORCE VECTORS that are carried by the charge. its direction or course is inward the center if its attra

It also refers to the physical field for a system of charged particles. Electric fields originate from electric charges, or from time-varying magnetic fields. Electric fields and magnetic fields are both manifestations of the electromagnetic force, one of the four fundamental forces (or interactions) of nature.

Electric Potential and Charge 15 A metal sphere (radius r 1) has an electrical potential that is equal everywhere on its surface radius R How to relate electric field, electric potential and electric charge? 1. Closed surface : begin with Gauss' Law Imagine drawing a Gaussian surface just outside the sphere 2. From Gauss' Law the flux is: Gaussian
