JEE Main 2015 — Capacitance Question with Solution

JEE Main 2015 (11 Apr Online)

Question

In the figure is shown a system of four capacitors connected across a 10 V battery. The charge that will flow from switch S when it is closed is:

Choose an option

Show full solutionCorrect option: C
Correct answer
C5 μC from b to a

Step-by-step explanation

Finally when switch is closed, 



q1=2×5=10 μC

q2=3×5=15 μC

The total charge on dotted region =q2-q1

=15-10=5 μC

Charge 5 μC flows from b to a
