1. The problem statement, all variables and given/known data At each point on the surface of a cube the electric field is parallel to the z axis. The length of each edge of the cube is 3.5 m. On the top face of the cube the electric field is in the negative z direction and has a magnitude of 37 N/C magnitude. On the bottom face of the cube the field is in the positive z direction and has a magnitude of 15 N/C. Determine the net charge contained within the cube. 3. The attempt at a solution The electric flux at the top face = EA = (-37 N/C)(3.5m)^2 = -453.25 N.m^2/C At the bottom face = (15 N/C)(3.5m)^2 = 183.75 N.m^2/C Gauss's law: flux * permittivity constant = charge Applied on cube: (net flux)(permittivity constant) = net charge (-269.5 Nm^2/C)(8.85*10^-12) = -2.385075 * 10^-9 C = -2385075 uC (micro) Both value and units are incorrect. > < "
