Question

Equipotentials at a large distance from a collection of charges whose total sum is not zero are ______.

Options

• spheres

• planes

• ellipsoids

• paraboloids

Answer 1

Equipotentials at a large distance from a collection of charges whose total sum is not zero are spheres.

Explanation:

A point charge is a collection of non-zero charges across a long distance. So, the potential is inversely proportional to the distance from the charge. As a result, all equally spaced points have identical electric potentials caused by a point charge. A sphere is the locus of these equally spaced points with the same potential.
