MCQ (Multiple Correct Answer)
In the circuit shown in figure initially key $K_1$ is closed and key $K_2$ is open. Then $K_1$ is opened and $K_2$ is closed (order is important). [Take $Q_1^{\prime}$ and $Q_2^{\prime}$ as charges on $C_1$ and $C_2$ and $V_1$ and $V_2$ as voltage respectively.]
Then,
A
charge on $C_1$ gets redistributed such that $V_1=V_2$
B
charge on $C_1$ gets redistributed such that $Q_1^{\prime}=Q_2^{\prime}$
C
charge on $C_1$ gets redistributed such that $C_1 V_1+C_2 V_2=C_1 E$
D
charge on $C_1$ gets redistributed such that $Q_1^{\prime}+Q_2^{\prime}=Q$
