The circuit was in the shown state for a long time. Now if the switch S is closed then the net charge that flows through the switch S, will be

A

`(400)/(3)muC`

B

`100 muC`

C

`(100)/(3) muC`

D

`50 muC`

Text Solution

Verified by Experts

The correct Answer is:
D

Initial and final charges are marked on `4 mu f` and `2 mu f` capacitors as shown
Hence charge passing through segment 1 and 2 are
`q_(1)=(100)/(3)muC rArr q_(1)=(50)/(3)muC`
`:.` charge through switch `=q_(1)+q_(2)=50 muC`.
