Homework Help: Science

Posted by Beth on Sunday, June 10, 2012 at 12:45pm.

The drawing shows an edge-on view of two planar surfaces thatintersect and are mutually perpendicular. Surface 1 has an area of 1.7 m^2, while surface 2 san area of 3.2 m^2. The electric field in the drawing is uniform andhas a magnitude of 250 N/C. Find the electrical flux through surface 1 and surface 2

I have tried to do the problem multiple amounts of time but I never seem to get the correct answer. For surface 1 its suppose to be 350 Nm^2/c and surface 2 is suppose to be 460 Nm^2/c. This is what I have gotten so far:

1: EACos(pheta) 250(1.7)(cos 55)= 9.4028 Nm^2/c
2: EACose(pheta) 250(3.2)(cos 35)= -722.95

Please help with anything you can!
