Question

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

• A. planes parallel to x y -plane
• B. planes parallel to y z -plane
• C. planes parallel to x z -plane
• D. coaxial cylinders of increasing radii around the x -axis

Answer 1

Answer: (B)

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