Question

A very large nonconducting plate lying in the xy-plane carries a charge per unit area of 9σ. A second such plate located at z = 4.40 cm and oriented parallel to the xy-plane carries a charge per unit area of −2σ. Find the electric field for the following.

(a) z < 0
σ/ε₀

(b) 0 < z < 4.40 cm
σ/ε₀

(c) z > 4.40 cm
σ/ε₀
