Q. The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface 1 has an area of 2.2 m2, while surface 2 has an area of 3.5 m2. The electric field E in the drawing is uniform and has a magnitude of 250 N/C. It is directed towards the two perpendicular surfaces, making an angle 35o with the bottom surface. Find the electric flux through (a) surface 1 and (b) surface 2.
