In the circuit shown in Fig. 2.4. initially key K1 is closed and key K2 is open. Then K1 is opened and K2 is closed (order is important). [Take Q1′ and Q2′ as charges on C1 and C2 and V1 and V2 as voltage respectively.]
Then
(a) charge on C1 gets redistributed such that V1 = V2
(b) charge on C1 gets redistributed such that Q1′ = Q2′
(c) charge on C1 gets redistributed such that C1V1 + C2V2 = C1 E
(d) charge on C1 gets redistributed such that Q1′ + Q2′ = Q
