Answer 1

Part 1: The magnitude of the electric field of an infinite line of chare is given by: E = zu 21ɛgR Where: 1 = -3 x 10-6- =-3 x 10-44 0.01m Then: -3 x 10-4 == -6.2 * 107 21(8.85 x 10-12) * 0.087 Part 2: Due to the symmetry, the y-axis is zero: Ez = 0 Part 3: The electric flux is: enc -ah (-3 x 10-4)(0.096) = -3.25 * 1064 EO EO 8.85 x 10-12 Part 4: The electric field due to the second charged line is: 2 1 9*10-4 = 3.72 * 108 21ɛR 21(8.85 x 10-12 * 0.0435) QE 3.25 * 106 Nm2 E = 20 TEOR
