Answer 1

HEYA MATE,

HERE IS UR ANSWER.

Thanks for asking this question.

Work done in moving a charge q coulomb on the surface of a given charged conductor of potential v is =q×v

I HOPE IT HELPS U.

Answer 2

An equipotential surface is one in which all the points are at the same electric potential. If a charge is to be moved between any two points (say from point A to point B) on an equipotential surface, according to the formula dW=q⋅dV
d
W
=
q
⋅
d
V
, the work done becomes zero.
