A point charge is placed at the centre of a spherical Gaussian surface. The electric flux through its surface is `1.5xx10^(4)" N-m"^(2)//C`. If the radius of the Gaussian surface is doubled. The flux passing through its surface will be

A

`1.5xx10^(4)"N-m"^(2)//C`

B

`3xx10^(4)"N-m"^(2)//C`

C

`6xx10^(4)"N-m"^(2)//C`

D

`20xx10^(4)"N-m"^(2)//C`

Text Solution

Verified by Experts

The correct Answer is:
A
`1.5xx10^(4)"N-m"^(2)//C`
Because flux is a number of lines crossing per unit surface area. So, it is independent of the radius of sphere.
