Physics - Capacitor Question with Solution | TestHub

In the circuit shown below, the switch $\mathrm{S}$ is connected to position $\mathrm{P}$ for a long time so that the charge on the capacitor becomes $q_1\mu \mathrm{C}$. Then $\mathrm{S}$ is switched to position $\mathrm{Q}$. After a long time, the charge on the capacitor is $q_2\mu \mathrm{C}$.

The magnitude of$q_2$is _____.
