Question

Derive relation for the work done to move a charge from infinity to a point against electric field.​

Answer 1

Answer:

Consider two points A and B at distances x and x + dx from the point O (Fig.) The negative sign indicates that the work is done against the electric force. The electric potential at the point P due to the charge +q is the total work done in moving a unit positive charge from infinity to that point.
