Assertion (A): Work done by electric field on moving a positive charge on an equipotential surface is always zero.
Reason (R): Electric lines of forces are always perpendicular to equipotential surfaces.
In the light of the above statements, choose the most appropriate answer from the options given below:
1
Both (A) and (R) are correct but (R) is not the correct explanation of
2
(A) is correct but (R) is not correct
3
(A) is not correct but (R) is correct
4
