The left most capacitor is uncharged. The other tow capacitors carry charges `q_1 = 8muC and q_2 = 10muC` . Now switch S is closed. Find the final charge on left most capacitor.

A

`3muC`

B

`6muC`

C

`12muC`

D

`18muC`

Text Solution

Verified by Experts

The correct Answer is:
B
Let charge `x` flow through circuit on closing swithc. Then final charge on each capacitor is as shown.
`(x)/(b)+(q_(1)+x)/(6)+(q_(2)+x)/(6)=6`

or `3x+q_(1)+q_(2)=36` or `x=6muC`
