RC Circuits: For the circuit shown in the figure, V = 60 V, C = 40 µF, R = 0.90 M?, and the battery is ideal. Initially the switch S is open and the capacitor is uncharged. The switch is then closed at time t = 0.00 s. At a given instant after closing the switch, the potential difference across the capacitor is twice the potential difference across the resistor. At that instant, what is the charge on the capacitor?
