Question
In the figure a butterfly net is in a uniform electric field of magnitude E = 2.5 mN/C. The rim, a circle of radius a = 8.0 cm, is aligned perpendicular to the field. The net contains no net charge. Find the magnitude of the electric flux through the netting.
I got -5.027 x 10?-5 N???/C but it is wrong.

Find the magnitude of the electric flux through the netting. I got - 5.027 x 10? - 5 N???/C but it is wrong.Explanation / Answer
electric flux phi = EA
phi = 0.0025 * 3.14 * 0.08*0.08
phi = + 5.024 *10^-5 Nm^2/C
