A point charge of 1.77 `muC` is at the centre of a cubical gaussian surface having each side 50 cm. what is the net electric flux through the surface?

Options

A. `10^(5)Nm^(2)C^(-1)`
B. `1.5xx10^(5)Nm^(2)C^(-1)`
C. `2xx10^(5)Nm^(2)C^(-1)`
D. `2.5xx10^(5)Nm^(2)C^(-1)`

Answer

C

Explanation

`phi_(E)=(q)/(epsi_(0))=(1.77xx10^(-6))/(8.85xx10^(-12))=2xx10^(5)Nm^(2)//C`
