Q. The box-like Gaussian surface encloses a net charge of +24.0ε0 C and lies in an electric field given by E = [(10.0 + 2.00x)i - 2.00j + 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?

Q. Two identical +9.5 uC point charges are initially 3.5 cm apart from each other. If they are released at the same instant from rest, how fast will each be moving when they are very far away from each other? Assume they have identical masses of 1.0 mg.
