Capacitor question

2025 · 29 Jan · Shift 2 · Q68

JEE MainPhysicsCapacitorMCQ+4 / −1
A capacitor, C1=6μFC_1 = 6 \mu FC1​=6μF is charged to a potential difference of V0=5VV_0 = 5VV0​=5V using a 5V battery. The battery is removed and another capacitor, C2=12μFC_2 = 12 \mu FC2​=12μF is inserted in place of the battery. When the switch 'S' is closed, the charge flows between the capacitors for some time until equilibrium condition is reached. What are the charges (q1q_1q1​ and q2q_2q2​) on the capacitors C1C_1C1​ and C2C_2C2​ when equilibrium condition is reached.
