Mark the wrong statement-

Options

A. Equipotential surface never cross and other
B. for a uniformly charged nonconducting sphere, the electric potential at the centre of the sphere is 1.5 times that at the surface
C. if potential in a certain region in non zero constant, then the electric field in that region will also be non zero constant
D. Inside a spherical uniformly charged shell, the electric field is zero but the electric potential is the same as that at the surface.

Answer

C
