A point charge of `2.0 muC` is at the centre of a cubic Gaussian surface 9.0 cm on edge. What is the net electric flux through the surface?

Explanation

Given, `q=2.0 muC=2.0xx10^(-6) C`
`epsi_(0)=8.854xx10^(-12) C^(2)-N^(-1) -m^(-2)`
The net flux through the surface,
`phi=q/epsi_(0)=(2xx10^(-6))/(8.854xx10^(-12))=2.26xx10^(5) N-m^(2) //C`
