In the figure initial status of capacitor and their connection is shown. Which of the following is incorrect about this circuit?

A) Final charge on each capacitor will be zero

B) Final total electrical energy of the capacitors will be zero

C) Total charge flown from A to D is \[30\mu C\]

D) Total charge flown from A to D is -\[30\mu C\]

Correct Answer: C

Solution :

[c] \[V=\frac{{{Q}_{1}}+{{Q}_{2}}}{{{C}_{1}}+{{C}_{2}}}=0\] Final potential difference = zero Final charge = zero Charge flow \[30\mu C\]from A to D
