1. Three non-conducting infinite planes of charge lie in the xy plane. Let o1 = 120.0 /C/m, 02 = -70.0 MC/m2, 03 = 80.0 C/m2, where plane 1 lies at z = 0.00 m, and plane 2 and 3 lie at z = 0.20 m and z = 0.35 m respectively. a) Use Gauss' law to derive the equation for the electric field due to a non-conducting plane of charge. b) What is the magnitude and direction of the electric field at z = 0.50 m? c) If you place a proton at z = 0.50 m and release it from rest, what acceleration will the proton experience
