Equipotential Surfaces

For the various charge Systems, we represent equipotential surfaces by curves and line of force by full line curves. Between any two adjacent equipotential surfaces, we assume a constant potential difference the equipotential surfaces of a single point charge are concentric spherical shells with their centres at the point charge. As the lines of force point radially outwards, so they are perpendicular to the equipotential surfaces at all points.

Identify the wrong statement.

A) Equipotential surface due to a single point charge is spherical.

B) Equipotential surface can be constructed for dipoles too.

C) The electric field is normal to the equipotential surface through the point.

D) The work done to move a test charge on the equipotential surface is positive.
