Problem C$2\mathrm{.}1()$: The capacitors shown right are both initially uncharged. The battery has $V=210V$ and the capacitances are $C_1=3F$ and $C_2=6F.$

Now an additional pair of capacitors is added to give the circuit diagram shown right.

$($c$)$ What is the potential difference across points $c$ and $d?$

Now the second switch $S_2$ is closed.

$($d$)$ What is the potential difference across each capacitor?

$($e$)$ How much charge flowed across $S_2$ when it was closed?
