Q2) Two real batteries of emfs &, = 2 V and Ɛ2 = 6 V and internal resistances r, = 0.40 N and r2 = 0.80 N, a capacitor of capacitance C = 20 µF and a switch S are placed within a circuit, as shown in the figure. What is the difference between the charge on the capacitor when the switch S is open and when it is closed? (10p) (In both cases assume that the switch is open or closed for a long time such that the current is stabilized.)
