Q S1

Q.- Two identical capacitors A and B, both having same capacitance C, are connected with battery of e.m.f. E as shown in figure. Initially both switches are open and initially capacitor B has charge CE coulomb as shown in figure and capacitor A is uncharged. Now switch S1 is closed and S2 is open till capacitor A becomes fully charged, then S1 is open and S2 is closed till flow of charge through battery is stopped. This process constitute one cycle. The cycle is repeated for a number of cycles. Read the above passage carefully and answer the following questions
(A) Charge on capacitor B after second cycle is?
(B) Total work done by the battery Q in 5 cycles is?
