Two capacitors A and B with capacitors `3 muF and 2 muF` are charged to a potential difference of 100 V and 180 V respectively. One plate of two capacitors are connected as shown. Now switch S is closed so as to connect a cell of 100 V to the free plates of two capacitors.
(a) Find charge on the two capacitors after the switch is closed.
(b) Calculate heat generated in the circuit
