A point charge of 2muC is at the centre ...

A point charge of `2muC` is at the centre of a cubical Gaussian surface 9cm on the edge. Calculate the net electric flux through the surface.

Text Solution

Verified by Experts

Given, `q=2muC= 2 xx 10^(-6)C`
and `epsi_(0)= 8.85 xx 10^(-12) C^(2)N^(-1) m^(-2)`
From Gauss.s theorem `phi_(E)`
`=(q)/(epsi_(0))= (2 xx 10^(-6))/(8.85 xx 10^(-12))`
`=2.26 xx 10^(5) N-m^(2)C^(-1)`
