The equipotential surfaces due to an isolated point charge q < 0 are

concentric spherical shells and distance between the shells increases with the distance from point charge concentric spherical shells and the distance between the shells decreases with the distance from the point charge equispaced concentric spherical shells concentric surfaces in elliptical shape

concentric spherical shells and distance between the shells increases with the distance from point charge

The correct answer is Option (1) → concentric spherical shells and distance between the shells increases with the distance from point charge
