The box-like Gaussian surface shown in Figure encloses a net charge of +24.0ε₀ C and lies in an electric field given by E = [(10.0 + 2.00x)i – 3.00j + bzk] N/C, with x and z in meters and b a constant. The bottom face is in the xz plane; the top face is in the horizontal plane passing through y₂ = 1.00 m. For x₁ = 1.00 m,x₂ = 4.00 m, z₁ = 1.00 m, and z₂ = 3.00 m, what is b?
