Energy Stored & Force between Plates

The electrostatic force ( $F$ ) between the metal plates of an isolated parallel plate capacitor ( $C$ ) having a charge $Q$ and area $A$ is ( $d$ = distance between the plates)

Show answer and solution

Answer: (c)

Each plate feels the field of the other plate only: $E' = \frac{\sigma}{2\varepsilon_0}$ .
$F = QE' = \frac{Q^2}{2\varepsilon_0 A}$
For an isolated capacitor $Q$ is fixed, and $d$ does not appear in $F$ .
So the answer is (c) independent of $d$ .
