Energy Stored & Force between Plates

The energy stored in a capacitor of capacity $C$ and potential $V$ is given by

Show answer and solution

Answer: (d)

Work done in charging: $U = \int_0^Q \frac{q}{C}\,dq = \frac{Q^2}{2C}$ .
With $Q = CV$ : $U = \frac{1}{2}CV^2$ .
So the answer is (d) $\frac{CV^2}{2}$ .
