A very large nonconducting plate lying in the xy-plane carries a charge per unit area of 90. A second such plate located at z = 3.35 cm and oriented parallel to the xy-plane carries a charge per unit area of -40. Find the electric field for the following. (a) z<0 olto (b) 0<z<3.35 cm σ/εο (c) z> 3.35 cm 30/50 A very large nonconducting plate lying in the xy-plane carries a charge per unit area of 90.
