The work done to move a charge along an equipotential from A to B

The work done to move a charge along equipotential from A to B

The work done to move a unit charge along an equipotential from P to Q

The work done to move a charge on an equipotenital surface is

STATEMENT-1 : Work done to move a charge on the surface of metal solid charged cylinder is always zero. and STATEMENT-2 : Work done to move a charge on an equipotential surface is zero.

Assertion(A): A point charge q is rotated along a circle around another point charge Q .The work done by electric field on the field on the rotating charge in half revolution is zero. Reason (R ) :No work is done to move a charge on an equipotential line or surface.

The work done in moving a positive charge on an equipotential surface is:
