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

Options

  1. Aplanes parallel to yzy z-plane
  2. Bplanes parallel to xyx y-plane
  3. Cplanes parallel to xzx z-plane
  4. Dcoaxial cylinders of increasing radii around the xx-axis.

Correct answer

A. planes parallel to yzy z-plane

Step-by-step solution

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 xx-direction is perpendicular only to yzy z plane.
