A cube of arranged such that its length ,breadth ,height are along`X,Y,Z` directions one of its corners is situated at the origin Length of each side of the cube is `25cm` .The components of electric field are `E_(x)=400sqrt(2)N//C` ,`E_(y)=0` and `E_(z)=0` respectively.Flux coming out of the cube at one end will be

Options

A. `25sqrt(2)Nm^(2)//C`
B. `5sqrt(2)Nm^(2)//C`
C. `250sqrt(2)Nm^(2)//C`
D. `25Nm^(2)//C`

Answer

A

Explanation

`barE_(1).barA_(1)+barE_(2)barA_(2)+barE_(3).barA_(3)=phi`
