Question:

The drawing shows an edge-on view of two planar surfaces that intersect and are mutually perpendicular. Surface 1 has an area of 1.7m2, while surface 2 has an area of 3.2 m2. The electric field E†’ in the drawing is uniform and has a magnitude of 250 N/C. Find the magnitude of the electric flux through
(a) Surface 1 and
(b) Surface2.
