A point charge causes an electric flux of ` -1.0 xx10^3 Nm^(-2)C^(-1)` to pass through a spherical Gaussian surface of 10.0 cm radius centred on the charge. If the radius of the Gaussian surface were three times, how much flux would pass through the surface

A

`3.0 xx10^3 Nm^2//C`

B

`-1.0 xx10^3 Nm^2//C`

C

`-3.0 xx10^3 Nm^2//C`

D

`-2.0 xx10^3 Nm^2//C`

Text Solution

Verified by Experts

The correct Answer is:
B
`phi =q/(epsilon_0)`
It does not depend on the radius of a Gaussian surface.
