Energy Stored & Force between Plates

The electrostatic force (FF) between the metal plates of an isolated parallel plate capacitor (CC) having a charge QQ and area AA is (dd = distance between the plates)

Show answer and solution

Answer: (c)

  1. Each plate feels the field of the other plate only: E′=σ2ε0E' = \frac{\sigma}{2\varepsilon_0}.
  2. F=QE′=Q22ε0AF = QE' = \frac{Q^2}{2\varepsilon_0 A}
  3. For an isolated capacitor QQ is fixed, and dd does not appear in FF.
  4. So the answer is (c) independent of dd.
