Question

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

Diagram

• A. $+48\mu C$
• B. $+80\mu C$
• C. $+40\mu C$
• D. $+32\mu C$

Answer 1

The correct option is A $+48\mu C$

For the $2\mu F$ and $3\mu F$ capacitro, equivalent capacitance is $5\mu F$
$\Rightarrow V=\frac{Q}{C}=16V$
Now, $q=C=48\mu C$
