Physics - Capacitor Question with Solution | TestHub

In the following circuit, switch ${\mathrm{S}}_1$ remains closed for a long time and switch ${\mathrm{S}}_2$ remains open. The system reaches a steady state. Now we close switch ${\mathrm{S}}_2$ also, keeping ${\mathrm{S}}_1$ close. In the new steady state the magnitude of change in charge on capacitor ${\mathrm{C}}_2$ of $2\mu \mathrm{F}$ is $\mathrm{q}\mu \mathrm{C}$. Find q.
