A point charge of `4 mu C` is at the centre of a cube gaussian surface whose each side is 2 cm. What is the net electric flux through the surface ?

Text Solution

Verified by Experts

`q = 4 mu C = 4 xx 10^(-6) C`
`epsilon_(0) = 8.854 xx 10^(-12) C^(2) N^(-1) m^(-2)`
`phi = (q)/(epsilon_(0)) = (4 xx 10^(-6))/(8.854 xx 10^(-12))`
`phi = 2.26 xx 10^(5) Nm^(2) C^(-1)`
