The work done on a charge depends on the change in its potential energy. When a charge q is rotated in a complete circular path around another charge Q, the initial and final potential energies of the charge are the same since electric potential does not depend on the path. Therefore, there is no change in potential energy, and the net work done on the charge is zero.
