Consider two concentric spherical surfaces `S_1` with radius a and `S_2` with radius 2a, both centered at the origin. There is a charge +q at the origin and there are no other charges. Compare the flux `phi_1` 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:
C
