Physics - Capacitor Question with Solution | TestHub

A capacitor ${\mathrm{C}}_1$ is charged up to a voltage $\mathrm{V}=$ $60\mathrm{V}$ by connecting it to battery $\mathrm{B}$ through switch (1), Now ${\mathrm{C}}_1$ is disconnected from battery and connected to a circuit consisting of two uncharged capacitors ${\mathrm{C}}_2=3.0\mu \mathrm{F}$ and ${\mathrm{C}}_3=6.0\mu \mathrm{F}$ through a switch $(2)$ as shown in the figure. The sum of final charges on ${\mathrm{C}}_2$ and ${\mathrm{C}}_3$ is:
