8. A series RC circuit (Fig. 1 below) with one resistor (R=500 M) and one capacitor
(C=0.5 µF) is connected to an AC voltage supply which supplies a voltage v=100
sin(1000t+309) (from t=0 to t=∞). The initial charge on the capacitor is Qo = 25 µC
and the initial voltage on the capacitor is in the same sense as the AC voltage supply.
