Question

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`

Answer 1

Correct Answer - 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`
