The equipotential surfaces due to an isolated point charge \( q < 0 \) are:
- A concentric spherical shells and distance between the shells increases with the distance from point charge
- B concentric spherical shells and the distance between the shells decreases with the distance from the point charge
- C equispaced concentric spherical shells
- D concentric surfaces in elliptical shape
Answer & Solution
Correct Answer
(A) concentric spherical shells and distance between the shells increases with the distance from point charge
Step-by-step Solution
Detailed explanation
Equipotential surfaces for a point charge are concentric spheres because the potential depends solely on the radial distance. Since the electric field strength decreases as you move away ( \(E \propto 1 / r^2\) ), the distance between shells must increase to maintain a constant…
