The work done in bringing a unit positive charge from infinity to the given point against the direction of electric intensity is

The work done in taking a unit positive charge from P to A is W_A and P to B is W_B . Then .

The work done in taking a unit positive charge from P to A is W_A and P to B is W_B . Then .

……………... is the work done in moving a unit positive charge from point A to B in an electric field.

Work done in moving a unit positive charge through a distance of x meter on an equipotential surface is :

Show that the work done by an external force in bringing a unit positive charge from infinity to a point is equal to electrostatic potential (V) at that point.

Electric potential at a point in an electric field is measured as the work done in bringing unit positive charge from infinity to that point:- The inetnsity of electric field at a point due to a point electric charge is 20NC^-1 and the electric potential at that point is 10 JC^-1 . Calculate the distance of the point from the charge.
