Equipotential surfaces associated with an electric field which is increasing in magnitude along the x-direction are

Options

A. planes parallel to `xy`-plane
B. planes parallel to `yz`-plane
C. planes parallel to `xz`-plane
D. coaxial cylinders of increasing radii around the x-axis

Answer

B

Explanation

Equipotential sutfaces are surfaces of constant electrical potential. The equipotential surfaces associted with an electric field which is increasing in magnitude along the x-direction are planes parallel to `yz`plane.
