The electric field in a particular region of space is everywhere parallel to the z axis. A box (L = w = h = 2.0 m) is in this region as shown in the figure below, and has a net charge qnet enclosed within it. On the front face of the box, the electric field points in the - direction and has a magnitude E₁ = 30 N/C. On the back face of the box, the electric field points in the +z direction and has a magnitude E₂ = 21 N/C. What is the value (magnitude and sign) of anet?
