Parallel Plate Capacitor
Question

In the circuit shown in the figure, there are two parallel plate capacitors each of capacitance C. The switch S1 is pressed first to fully charge the capacitor C1 and then released. The switch S2 is then pressed to charge the capacitor C2. After long time, S2 is released and then S3 is pressed. After long time, 

 

the charge on the upper plate of C1 is CV0

the charge on the upper plate of C1 is 2CV0

the charge flown through rightmost battery is 2CVo

the charge on the upper plate of C2 is –CV0
