(D) When two capacitors are connected such that their potential becomes zero,it implies that the total charge on the plates connected together must be zero.Let the charges on the capacitors be $Q_1 = C_1 V_1$ and $Q_2 = C_2 V_2$.For the potential to become zero upon connection,the charges must be equal in magnitude and opposite in sign,such that $Q_1 + Q_2 = 0$,which means $C_1 V_1 = C_2 V_2$.Given $V_1 = 120\, V$ and $V_2 = 200\, V$,we have:$120 C_1 = 200 C_2$Dividing both sides by $40$:$3 C_1 = 5 C_2$

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