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

Explanation

Net electric flux `(phi_(Net))` through the cubic surface is given by,
`phi_(Net)=(q)/(in_(0))`
Where,
`in_(0)` = Permittivity of free space
`=8.854xx10^(-12)N^(-1)C^(2)m^(-2)`
q = Net charge contained inside the cube = `2.0muC=2xx10^(-6)C` ltBrgt `thereforephi_(Net)=(2xx10^(-6))/(8.854xx10^(-12))`
`=2.26xx10^(5)Nm^(2)C^(-1)`
he net electric flux through the surface is `2.26xx10^(5)Nm^(2)C^(-1)`.
