Question

In the given circuit, a charge of $+80\mu C$ is given to upper plate of a $4\mu F$ capacitor. At steady state the charge on the upper plate of the $3\mu F$ capacitor is:

• A. $60\mu C$
• B. $48\mu C$
• C. $80\mu C$
• D. $0\mu C$

Answer 1

The correct option is B $48\mu C$

$Q_1:Q_2=2:3$
$Q_2=\frac{3}{5}\times 80=48\mu C$
