Combination of Capacitors

Four capacitors are connected to a battery as shown in figure. The ratio of charges on capacitors $C_2$ and $C_4$ is

Show answer and solution

Answer: (b)

$C_4 = 4C$ is directly across $V$ : $Q_4 = 4CV$ .
$C_3, C_2, C_1$ ( $3C, 2C, C$ ) are in series across $V$ : $\frac{1}{C_s} = \frac{1}{3C} + \frac{1}{2C} + \frac{1}{C} = \frac{11}{6C} \Rightarrow C_s = \frac{6C}{11}$ .
$Q_2 = \frac{6CV}{11}$ .
$\frac{Q_2}{Q_4} = \frac{6/11}{4} = \frac{3}{22}$ . So the answer is (b).
