There is a point charge Q at a distance R/2 from the centre of a circle of radius R. Another point charge q is to be moved from A to B, where A and B are two diametrically opposite points on the circle. How much work is done by the electrostatic force exerted by Q on q?

Dear abhingya

A And B are diametrically opposite points on the circle...Work done by electrostatic force is zero.
