The electric charges are distributed in a small volume. The flux of the electric field through a surface of radius 10 cm surrounding the total charge is 20 Vm. The flux over a concentric sphere of radius 20 cm will be

A

`20 Vm`

B

` 25 V m `

C

` 40 V m `

D

` 200 V m `

Text Solution

Verified by Experts

The correct Answer is:
A
Since charge enclosed remains the same, hence as per Gauss. law total electric flux remains uncharged at 20 V m inspite of the increase in surface area.
