A capacitor, C1, is charged using a 6.3 V battery. C1 has a capacitance of 3.55μF

1) When this capacitor/battery circuit reaches equilibrium, what is the charge on each place of the capacitor?

2) When C1 is fully charged, the battery is removed and C1 is put into a circuit with a switch and another capacitor C2 which has a capacitance of 8.95μF but is initially uncharged. (figure below) When switch S is closed, the charge from C1 is redistributed between the capacitors until they have reached the same potential. What is the final potential V?
