Physics Question from JEE Main 2025 · 29 January, Shift 2

A capacitor, C1=6 μFC_1 = 6 \, \mu F, is charged to a potential difference of V1=5 VV_1 = 5 \, V using a 5V5V battery. The battery is removed and another capacitor, C2=12 μFC_2 = 12 \, \mu F, 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_1 and q2q_2 on the capacitors C1C_1 and C2C_2 when equilibrium condition is reached?

  • A

    q1=15 μC, q2=30 μCq_1 = 15 \, \mu C, \, q_2 = 30 \, \mu C

  • B

    q1=30 μC, q2=15 μCq_1 = 30 \, \mu C, \, q_2 = 15 \, \mu C

  • C

    q1=10 μC, q2=20 μCq_1 = 10 \, \mu C, \, q_2 = 20 \, \mu C

  • D

    q1=20 μC, q2=10 μCq_1 = 20 \, \mu C, \, q_2 = 10 \, \mu C
