A uniform electric field of magnitude 2.40 103 N/C points upward.An empty, closed shoe box has a top and bottom that are 35.0 cm by21.0 cm, vertical ends that are 21.0 cm by 20.0 cm, and verticalsides that are 20.0 cm by 35.0 cm.
(a) Select the list which correctly describes the direction ofelectric flux through the top, bottom, vertical ends and verticalsides of the box, in that order.
1. outward, outward, outward, outward
2. inward, inward, inward, inward
3. outward, outward, none, none
4.inward, inward, none, none
5. none, none, outward, outward
6. none, none, inward, inward
7. outward, inward, none, none
8. inward, outward, none, none
9. none, none, inward, outward
10. none, none, outward, inward
(b) Calculate the electric flux (magnitude and sign) through eachof the six sides of the box.
top ______ N · m2/C
bottom _____ N · m2/C
vertical ends ______N · m2/C
vertical sides ______ N · m2/C
