Question

If a unit positive charge is taken from one point to another over an equipotential surface, then, work is done on the charge, work is done by the charge, work done is constant, no work is done.

Since the potential at each point of an equipotential surface is the same, the potential does not change while we move a unit positive charge from one point to another. Therefore work done in the process is zero.
