`S_(1)` and `S_(2)` are two equipotential surfaces on which the potentials are not equal

Options

A. `s_(1)` and `s_(2)` cannot intersect
B. `s_(1)` and `s_(2)` cannot both be plane surfaces
C. In the region between `s_(1)` and `s_(2)` , the field is maximum where they are closest to each other
D. A line of force from `s_(1)` and `s_(2)` must be perpendicular to both

Answer

A, C, D

Explanation

`S_1 and S_2` can’t intersect because their potentials are not same.
`| vec E|=|(Delta V)/(Delta r)|` (D) Field lines are always perpendicular to equipotential surface.
