Combination of Capacitors

Two parallel plate air capacitors are connected in parallel. Each capacitor has plate area $A/2$ and separation between the plates is $d$ and $2d$ respectively. The equivalent capacity of the combination is

( $\epsilon_0$ = absolute permittivity of free space)

Show answer and solution

Answer: (b)

Parallel: $C = \frac{\epsilon_0 (A/2)}{d} + \frac{\epsilon_0 (A/2)}{2d}$ .
$C = \frac{A\epsilon_0}{2d}\left(1 + \frac{1}{2}\right) = \frac{3A\epsilon_0}{4d}$
So the answer is (b).
