The figure shows capacitor 1 (C1 = 6.21 μF), capacitor 2 (C2 = 7.92 μF), and capacitor 3 (C3 = 8.14 μF) connected to a 13.7 V battery. When switch S is closed so as to connect uncharged capacitor 4 (C4 = 7.45 μF), (a) how much charge passes through point P from the battery and (b) how much charge shows up on capacitor 4? (a) Number Units (b) Number Units
