1. The problem statement, all variables and given/known data A butterfly net hangs from a circular loop of diameter 400 mm . You hold the loop horizontally in a region where the electric field is 150 N/C downward, as shown in (Figure 1) . What is the electric flux through the net? 2. Relevant equations k = 9E9 N E = kq/r2 Flux = Q enclosed / E0 Flux = EA 3. The attempt at a solution r = .195 m 150 = k(q)/(.2)2 q = 6.667E-10 Flux = 6.667e-10/8.85E-12 Flux = 75.3 Mastering Physics says this is wrong. Please help?
