a  Q to R
b  S to the battery
c  What is the pd across C1 and C2
d  What is capacitance of C2
e  What is the single capacitor which is equivalent to C1 and C2 in series and what charge would it store?

a. 4uC b. 4uC c. 6V d. \[Q = C _{eq}V\] \[\frac{ 1 }{ C _{eq}} = \frac{ 1 }{ C _{1}}+\frac{ 1 }{ C _{2}}\] \[Q = ( \frac{ 1 }{ C _{1}}+\frac{ 1 }{ C _{2}})^{1}V\]

if +4uC is on the plate at P then 4uC will be on the plate at Q meaning +4uC flowed to the plate at R meaning that there's  4 uC at the plate at S meaning +4uC flowed to the terminal of the battery. For c. ) I did the total voltage drop, which must be 6V, you could also do the drop per capacitor, and then find the capacitance of c2 from that. I didn't do it that way, I combined the solution to d and e into one part instead.
