The drawing shows an edgeon 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!

Dan,
close, you need to change your theta.
A) 250(1.7)cos35
B) 250(3.2)cos55
this will work, just did it for my homework and they are correct. My E and A are different but the theta was the same.

CombatVetUSMC,
changed my login from the above entry.
A) 250(1.7)cos35 = 348.13 Nm2/C
B) 250(3.2)cos55 = 458.86 Nm2/C
Hopefully this works for you
