Could you show me your working?

vincent-lyon.fr · Answer

As C2 and C3 are in series, the same current passed through them, so they must bear the same charge:

$\large Q_2=Q_3$

using this, and basic electricity laws, you should be able to solve your problem.

Do you have your answer now?

anonymous · Answer

Hi @Vincent-Lyon.Fr, yeah it becomes clear that the potential difference must be less than $ V_0 $ since the voltage goes to other capacitors as well. Now I'm searching on the correct formula to get the numerical answer. While you're at it, I wonder if you can help me on this part.
