A point charge q is rotated along a circular path within the electric field produced by a second point charge Q . During one complete revolution, the work done by the electric field on the rotating charge is

Step-by-step solution

The electric field produced by a point charge Q is an electrostatic field, which is conservative in nature. For any conservative field, the work done by the field in moving a particle along a closed path is always zero, E d l = 0 . Since one complete revolution along a circular path forms a closed loop, the total work done by the electric field on the charge q is zero, irrespective of the position of the charge Q .
