Energy Stored & Force between Plates

A parallel plate air capacitor having area of each plate ' $A$ ' and the distance between the plates ' $d$ ' has uniform electric field E in the space between the plates. The energy stored in the capacitor is ( $\epsilon_0$ = permittivity of free space.)

Show answer and solution

Answer: (c)

Energy density $u = \frac{1}{2}\varepsilon_0 E^2$ .
Volume between plates $= Ad$ , so $U = \frac{1}{2}\varepsilon_0 E^2 Ad$ .
So the answer is (c) $\frac{1}{2}A\epsilon_0 E^2 d$ .
