2. Rotating field (6 points) A square with sides / = 3.3 m is positioned horizontally, that is, in the x-y plane, as shown in the figure below. A large, uniformly charged plate (not shown) generates a constant electric field with magnitude E = 2.8 N/C. The orientation of the plate is adjustable and allows the direction of the electric field to be varied. (a) (2 points) Suppose the electric field is in the y direction, as shown in figure (a). What is the electric flux through the square? (b) (2 points) Suppose the electric field is in the y-z plane, directed 45 upward from the y axis toward the z axis, as shown in figure (b). What is the electric flux through the square? (c) (2 points) What is the maximum electric flux through the square? How should the electric field be oriented in order to obtain this maximum electric flux? Z. E E 45 y
