Question:
In the circuit shown in the figure, the total charge in $750 \mu \mathrm{C}$ and the voltage across capacitor $\mathrm{C}_{2}$ is $20 \mathrm{~V}$. Then the charge on capacitor $\mathrm{C}_{2}$ is :
Correct Option: 1
Solution:
$\mathrm{q}_{3}=20 \times 8=160 \mu \mathrm{C}$
$\therefore \mathrm{q}_{2}=750-160=590 \mu \mathrm{C}$
