Question

In the circuit shown below, the switch $S$ is connected to position $P$ for a long time so that the charge on the capacitor becomes $q_1\mu C$. Then $S$ is switched to position $Q$. After a long time, the charge on the capacitor is $q_2\mu C$.

The magnitude of $q_2$ is ____.

Answer 1

Answer: 0.67

After long time $i$ circuit $=\frac{2}{3}$ ampere

$v_{AB}=2-2\left(\frac{2}{3}\right)=\frac{2}{3}$ volt
So, $q_2=CV=(1)\left(\frac{2}{3}\right)=\frac{2}{3}\mu C$
