A point charge `4muC` is at the centre of a cubic Gaussian surface 10 cm on edge. Net electric flux through the surface is

A

`2.5xx10^(5)Nm^(2)C^(-1)`

B

`4.5xx10^(5)Nm^(2)C^(-1)`

C

`4.5xx10^(6)Nm^(2)C^(-1)`

D

`2.5xx10^(6)Nm^(2)C^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
Here, `q=4muC=4xx10^(-6)C,l=10cm`
`phi=q/epsilon_(0)=(4xx10^(-6))/(8.85xx10^(-12))=4.5xx10^(5)Nm^(2)C^(-1)`
