Which of the following is correct regarding equipotential surface ?

A

Equipotential surfaces can never cross each other otherwise potential at a point will have two values which is absurd

B

Equitential surfaces are always perpendicular to lines of force

C

If a charge is moved from one point to the other over an equipotential surface, work done will be zero as
`W_(AB) = - U_(AB) = Q(V_(B) - V_(A) = 0 (as (V_(B) = V_(A))`

D

All options are correct
