QJEEM22Ph9956: JEE Main 2022 Physics - Class 12 JEEM22Ph9956 Solution: A capacitor C 1 of capacitance 5 F is charged to a potential of …

A capacitor C1 of capacitance 5 μ\mu F is charged to a potential of 30 V using a battery. The battery is then removed and the charged capacitor is connected to an uncharged capacitor C2 of capacitance 10 μ\mu F as shown in figure. When the switch is closed charge flows between the capacitors. At equilibrium, the charge on the capacitor C2 is __________ μ\mu C.

Step-by-Step Verified Solution

JEE Main 2022 (Online) 28th June Evening Shift Physics - Capacitor Question 66 English Explanation

Let the charge q is flown in the circuit.

So using Kirchhoff's law,

q10=150−q5{q \over {10}} = {{150 - q} \over 5}

q=100 μCq = 100\,\mu C
