Question

In the 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

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

Answer 1

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

let q be the charge on $3\mu F$ capacitor then
$⟹\frac{80-q}{2}=\frac{q}{3}$
$q=48\mu C$
