Question

If charge on left of the 5 $\mu F$ capacitor in the circuit segment shown in the figure is - 18 $\mu C$. The charge on the right plate of $3\mu F$ capacitor is

• A. $-6\mu C$
• B. $-12\mu C$
• C. $-18\mu C$
• D. $+6\mu C$

Answer 1

The correct option is D

$+6\mu C$

$\frac{Q_1}{C_1}=\frac{Q_2}{C_2}{Q}_2=2Q_1\&Q_1+Q_2=18\mu C\Rightarrow Q_1=6\mu C\&Q_2=12\mu C$
