Physics Question from JEE Main 2024 · 29 January, Shift 2

In the given figure, the charge stored in a $6\,\mu\text{F}$ capacitor, when points $A$ and $B$ are joined by a connecting wire, is $\mu\text{C}$:

The figure shows: a terminal marked $9\,\text{V}$ at the top feeds a horizontal top rail. Two vertical branches hang from that top rail down to a common horizontal bottom rail, and the bottom rail is earthed. Descending the left branch: a $6\,\Omega$ resistor, then the point $A$, then a $3\,\mu\text{F}$ capacitor, then the bottom rail. Descending the right branch: a $6\,\mu\text{F}$ capacitor, then the point $B$, then a $3\,\Omega$ resistor, then the bottom rail. $A$ and $B$ are thus the mid-points of the two branches, and they are the points joined by the connecting wire.
