56. Capacitors with electric capacitances C1 = 2 μF, C2 = 2 μF, C3 = 3 μF and C4 = 1 μF are connected as shown in Fig. The potential difference on the plates of the fourth capacitor is U4 = 100 V. Find the charges and potential differences on the plates of each capacitor, as well as the total charge and potential difference of the capacitor bank.
