Question

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

Step-by-Step Solution

For an isolated capacitor, charge QQ is constant. The force between the plates is given by Fplate=Q22Aϵ0F_{\text{plate}} = \frac{Q^2}{2A\epsilon_0}. This expression does not contain the distance between the plates, hence it is independent of the distance.
