Kirchhoff's Current Law

What are the charges and voltage drops across each capacitor?

What is the total energy stored by the 36 $\mu$F capacitor?

If the potential difference across the 20 $\mu$F capacitor is 12 V. What is the potential difference supplied by the battery? How much energy is stored in the 25 $\mu$F capacitor?

A circuit has the following R = 10 k$\Omega$, C = 25 $\mu$F, $\epsilon$ = 12 V.

How long will it take to charge the capacitor, C, to 10 V ?

How much current is flowing in the circuit at that time?
