(a) Find the flux through the whole surface of the cube Your response differs from the correct answer by more than 10%. Double check your calculations. N . mic (b) Find the flux through each face of the cube N m2/c answers to parts (a) or (b) change if the charge were not at the center? (Select all that apply.)

Answer 1

(c) Only (b) would change.

(a) would not change, because the same charge is still enclosed by the cube, $\phi_{cube}=\frac{Q_{enclosed}}{\epsilon_{o}}$ remains the same.

(b) changes because the position of the charge is no longer symmetric with respect to all the surfaces of the cube .
