Charge Sharing & Loss of Energy

Two capacitors $C_1$ and $C_2$ are charged to $120\text{ V}$ and $200\text{ V}$ respectively. It is found that connecting them together the potential on each one can be made zero. Then

Show answer and solution

Answer: (b)

Potential becomes zero only if opposite plates are joined and the charges cancel: $Q_1 = Q_2$ .
$120C_1 = 200C_2$
$3C_1 = 5C_2$ , so the answer is (b).
