(adsbygoogle = window.adsbygoogle || []).push({}); A uniform electric field of 25kN/C is directed parallel to the z-axis. A square of sides 5.0 cm is submersed in this field and initially located in the xy-plane. (a) Determine the electric flux for the square. (b) Repeat if the square is rotated 40.0 degrees about the x-axis. (c) Repeat if the square is moved again and this time its normal is parallel to the x-axis.

(a) 25*10^3 N/C * (5.0*10^-2 m)^2 = 62.5 = 63 Nm^2/C (this is right)

I don't understand how to set up (b) or (c). I'm trying to visualize rotating the square about the x-axis, but doesn't that make only four very slender slices of the square come in contact with the z-axis directed field?

answers:

1. a. 63 N m2/C

b. 48 N m2/C

c. 0
