In steady state, find the charge on `3muF` capacitor in `muC`

Options

A. 1
B. 2
C. 3
D. 4

Answer

D

Explanation

Let the potentials in steady state at various points be as shown
Sum of charges on all three capacitors will be zero.
So, `2(x-5)+3(x-1)+4(x-2)=0`
Solving `x=(7)/(3)`volts
So, Q(on `3muF`) `=3((7)/(3)-1)muC=4muC`.
