Q. The electrostatic force between the metal plates of an isolated parallel plate capacitor C having a charge Q and area A, is
A) proportional to the square root of the distance between the plates.
B) linearly proportional to the distance between the plates.
C) independent of the distance between the plates.
D) inversely proportional to the distance between the plates.
Explanation
[Solution] $F = \frac{Q^2}{2\epsilon_0A}$, independent of plate separation. Answer (3).
