Energy Stored & Force between Plates

A capacitor of capacitance C has charge Q and energy stored in it is W. If the charge is increased to 3Q, the energy stored in the capacitor W' will be

Show answer and solution

Answer: (a)

$W = \frac{Q^2}{2C} \propto Q^2$ for fixed $C$ .
$Q \to 3Q \Rightarrow W' = 9W$
So the answer is (a) $9W$ .
