1. The problem statement, all variables and given/known data In a cubical volume, 1.05 m on a side, the electric field is given by the formula below, where E0 = 1.25 N/C and a = 1.05 m. = E0(1 + z/a) i + E0(z/a) j The cube has its sides parallel to the coordinate axes, see the figure. Determine the net charge within the cube. 2. Relevant equations φe = ∫E⋅dA = qenc/ε0 3. The attempt at a solution So I know that I need to calculate the net flux through all the 6 faces of the cube in order to solve for qenc. I know that φ+z and φ-z are equal to 0. I think I am doing something wrong because it seems like they would cancel out? φ+x = E0 a2 ∫ (1+z/a) dz φ-x = -E0 a2 ∫ (1+z/a) dz φ+y = E0 a2 ∫ (z/a) dz φ-y = -E0 a2 ∫ (z/a) dz Also, I would evaluate the integrals from 0 to a right?
