Find the charge on 2 μ F .

Find the charge on $2 \mu \mathrm{F}$.

Step-by-step solution

Let potential of A$is zero and that of$B$is$V$. Applying charge conservation on given circuit.$$\begin{aligned} & 1(V-10)+2(V-0)+5(V-10)=0 \\ & 8 V-60=0 \\ & V=\frac{60}{8}=7.5 \text{ volt }\end{aligned}$$So charge on$2 \mu $\mathrm{F}=$2 \times 7.5=15 \mu $\mathrm{C}$
