Walker, Halliday & Resnick — Gauss' Law: Problem 13

13 The cube in Fig. 23-29 has edge length 1.40 m and is oriented as shown in a region of uniform electric field. Find the electric flux through the right face if the electric field, in newtons per coulomb, is given by (a) $18.0\hat{i}$, (b) $-2.00\hat{j}$, and (c) $-26.0\hat{i} + 4.00\hat{k}$. (d) What is the total flux through the cube for each field? (e) What is the total flux if the edge length is doubled?
