Question

Electric field in space is E = xi, find the electric flux passing through the
whole cube and through its individual faces. Side length of cube is 'a' and its
edges are parallel to the coordinate axis.

Answer 1

answer: A^3

explanation;

cube have faces

up and down, and also face to face surface have

fluxe = 0

and side wise side have 2 face, one face is equal to 0 and other E = ai^

E = a×area

= a×a^2

= a^3

then answer is a^3
