Consider the circuit shown in figure, after switch S is closed.

What amount of charge will flow through the switch?

A

`20 muC`

B

`60 muC`

C

`40 muC`

D

no charge will flow

Text Solution

Verified by Experts

The correct Answer is:
A
Figure (a) corresponds to when switch is open.
Figure (b) corresponds to when switch is closed.
.
.
Varous charges flowing after closing the switch are as follows:
`Deltaq_(1)=60-40=20 muC`
`Deltaq_(2)=20-0=20 muC`
`Deltaq_(3)=20-0=20 muC`
`Deltaq_(4)=Deltaq_(1)+Deltaq_(2)+Deltaq_(3) =60muC`.
