the cube of insulating material has the one corner at the origen . each side of the cube has length 0.250m so the top face of the cube is parallel to the xz-plane and is at y=.250m. it is observed that there is an electric field =(3280n/c*m)yj that is in the +y direction and whose magnitud depends only on y
what is the flux throught the top
calculated the net charge enclosed by the cube
