일반물리학 2 — Gauss' Law: Problem 15

15 Fig. 23-29 shows a Gaussian surface in the shape of a cube with edge length 5.60 m. What are (a) the net flux \(\Phi\) through the surface and (b) the net charge \(q_{enc}\) enclosed by the surface if \(\vec{E} = (3.00y \hat{j})\text{ N/C}\), with \(y\) in meters? What are (c) \(\Phi\) and (d) \(q_{enc}\) if \(\vec{E} = [-17.0 \hat{i} + (6.00 + 3.00y) \hat{j}]\text{ N/C}\)?
