Question

A charge of 160 µC is at the centerof a cube of edge 85.0 cm. No othercharges are nearby. (a) Find the total flux through each face ofthe cube.
____________ N·m2/C

(b) Find the flux through the whole surface of the cube.
____________ N·m2/C
(c) Would your answers to parts (a) or (b) change if the chargewere not at the center? (Select all that apply.) (a)would change
(b) wouldchange
   neitherwould change

Explain.

Explanation / Answer

b, The flux through thw whole surface is =Q/o = 18 079 096 Nm^2/C a, Since the cube has 6 sides, the flux through one side is/6 = 3 013 183 Nm^2/C c, If the charge was not at the centre, the result for part bstay unchanged because it doesn't depend on the position of charge.But the result for a will change because the flux through sides areno longer equal to each other, so we can't devide by 6
