Problem

Capacitors of

2\,\mu\text{F}

and

6\,\mu\text{F}

are connected in parallel. This combination is connected in series with a

5\,\mu\text{F}

capacitor. If the charge on the

5\,\mu\text{F}

capacitor is

30\,\mu\text{C}

, the emf of the battery connected across the network is closest to a)

6.0\,\text{V}

9.8\,\text{V}

48\,\text{V}

15\,\text{V}
