no work is done in moving a test charge over an equipotential surface why
and whats the meaning of equipotential

Expert Answer
Equipotential means that the surface has equaal potential (or equal voltage) all over its surface.
So, if a test charge is present on it, there is no change in potential encountered by the charge. Since, there is no change in potential, no force is done to move it.
Since there is no force acting, there is no work required to keep moving the charge over the surface.
Hence, no work is done to move a test charge over an equipotential surface.
We can also make use of the following equation of work done.
dW = q dV
Since dV = 0
dW = 0
