Problem 2 Consider the Gaussian surfaoe shown in Figure 2. A uniform external electric eld 31 having magnitude 3.20 x 103 NIC and parallel to the 12 plane with an angle of 36.8?" measured from the +1: axis toward the +2 axis, enters through face 1 {back face}. In addition, a uniform electric eld E2 of magnitude 6.40 x 103 NH: traveling in the same direction g 31 i ows outwardly through face 2 (front face). an. it Figure 2. Gaussian surface in the form of a prism through which two fields pass.
