Question

Consider the situation shown in the figure. The capacitor $\text{A}$ has a charge $q$ on it where capacitor $\text{B}$ is uncharged. The charge appearing on the capacitor $\text{B}$ a long time after the switch is closed is

• A. $2q$
• B. $q$
• C. $\frac{q}{2}$
• D. $0$

Answer 1

The correct option is D $0$

When the switch is closed, inner plates of the two capacitors are connected with each other. But outer plates are not connected. It means circuit is not completed. Therefore no charge will appear on $\text{B}$
