An imaginary closed cube-shaped surface on the L side is in a region where there is a uniform electric field ?. What is the electrical flow through each face of the cube and the total flow through the cube when: (a) it is oriented with two of its faces perpendicular to ? (Figure a) and (b) it undergoes a rotation of an angle θ in around a vertical axis (Figure b).
