Electricity

The circuit of Fig. 28-56 shows a capacitor C, two ideal batteries, two resistors, and a switch S. Initially S has been open for a long time. If it is then closed for a long time, by how much does the charge on the capacitor change? Assume C = 15 µF, 1 = 1.0 V, 2 = 3.0 V, R1 = 0.40 , and R2 = 0.50 .
