Three uncharged capacitors of capacitance `C_1,C_2` and `C_3` are connected to one another as shown in figure. The potential at `O` will be

A

`3V`

B

`49/11V`

C

`4V`

D

`3/11V`

Text Solution

Verified by Experts

The correct Answer is:
B
In the figure `q_1+q_2+q_3=0`
`60(V-6)+20(V-2)+30(V-3)=0`
solving this equation we get
`V=49/11V`
