In the above question, what is the electric flux passing throguh a face of the given cube ?

Answer

`9.42 NC^(-1) m^(2)`

Explanation

The given charge is located at one corner of the cube. So it is being directly shared by three faces of the cube.
Electric flux throgh any one of these faces
`phi = (1)/(3) xx ((1)/(8) (q)/(in_(0))) = (1)/(3) xx28.25 NC^(-1) m^(2)`
