An electric field given by E = 4.0i -3.0 (y^2 +2.0 ) j pierces a Gaussian cube of edgr length 2 m and positioned as shown in the figure. ( The magnitude E is in newtons per coulomb and the position x is in meters.) What is the electric flux through the (a) top face, (b) what is the net electric flux through the cube ?
