Conside r two concentric spherical surface `S_(1)` with radius `a` and `S_(2)` with radius `2a` ,both centred on the origin. There is a charge `+q` at the origin, and no other charges.Compare the flux `phi` through `S_(1) with the flux `phi_(2)` through `S_(2)`.

A

`phi_(1)=4phi_(2)`

B

`phi_(1)=2phi_(2)`

C

`phi_(1)=phi_(2)`

D

`phi_(1)=phi_(2)//2`

Text Solution

Verified by Experts

The correct Answer is:
3
Flux through both will be same as net charge enclosed by both is same
