The magnitude of the uniform electric fields on 5 of the 6 faces of the rectangular box are E₁ = 142 N/C, E₂ = 208 N/C, E₃ = 124 N/C, E₄ = 185 N/C, and E₅ = 124 N/C. All the field
a. E₆ = 208 N/C
b. The total electric flux through the box is 860 Nm²/C
c. The electric field on the sixth face of the box is directed opposite to the field on the second face
d. The electric field on the sixth face of the box is directed in the same direction as the field on the second face
