We have two capacitors `C_1 and C_2` of capacitance `12 muF` and `6 muF` respectively. As shown in the given circuit arrangement the two capacitors are joined to a power supply of 6 volts. Initially the switch `S_1` is closed but switch `S_2` is open. After some time, the switch `S_1` is opened and simultaneously switch `S_2` is closed.
Now answer the following questions :
The final value of charge on capacitor `C_2` is

Options

A. `24 muC`
B. `48 mu C`
C. `72 mu C`
D. `12 mu C`

Answer

A

Explanation

Final value of charge on capacitor `C_2, q_2 = C_2 V = 6 mu F xx 4 V = 24 mu C`
