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

Options

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

Answer

A

Explanation

Any surface which has same electrostatic potential at every point is called an equipotential surface.Electric field is always perpendicular to an equipotential surface.therefore x-direction is perpendicular only to yz plane
