Question

The equipotential surfaces around an isolated point charge are:

विकल्प

• Parallel planes passing through the charge

• Concentric cubes centered on the point charge

• Concentric spheres around the point charge

• Coaxial cylinders around the point charge

Answer 1

Since the potential due to a point charge depends only on the distance \[r\] and not on direction (spherically symmetric), all points at the same distance have the same potential. Hence, the equipotential surfaces are concentric spheres around the point charge.
