What is the potential difference across C2 when C1 = 5.0 µF, C2 = 15 µF, C3 = 30 µF, and V0 = 24 V?

2. Relevant equations

C = Q/V

3. The attempt at a solution

I calculated total capacitance of C1 and C3 in parallel, that is 3.5 x 10^-5 Farads.

So the charge going across is Q = CV = 3.5x10^-5 x 24 = 8.4 x 10^-4 C

Therefore the voltage going across the other capacitor is V = Q/C, which 8.4x10^-4/15x10^-6 = 56V

Which looks really wrong.

Help?

Thanks in advance.
