Unformatted text preview: Hint: Apply the Divergence Theorem and the integral form of Gauss’ Law. We could compute the electric ﬁeld and evaluate surface integrals over the 6 sides of the cube. (A tedious task in this case.) But we know the requested integral is equal to charge inclosed (Gauss’ Law), so we just evaluate the volume integral: L Z L Z L Z ρ xyz L 3 d x d y d z = ρ L 3 8 ε 4. There should be lots of time to start the homework problems. Encourage the students to get each of the three problems at least set up. Note 3.19 requires MatLab plots. 5.
