The box-like Gaussian surface of Figure encloses a net charge of + 24.0?₀ C and lies in an electric field given by E = [(10.0 +2.00x)i - 3.00j + bzk/N/C, with x and 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 = 1.00m, x₂ = 4.00 m, z₁ = 1.00 m, and z₂ = 3.00 m, what is b?
