In Figure a cube of insulating material has one corner at the origin. Each side of the cube has length 0.020 m, so the top face of the cube is parallel to the xz-plane and is at y=0.02 m.It is observed that there is an electric field E=(7960 N/C.m)y j, that is in the+y direction and whose magnitude depends only on y. use Gauss,s Law to calculate the net charge enclosed by the cube.

(Note; eo=8.854x10-12 C2/N.m2)
