Unformatted text preview: F out of the box is 0. b) If is a sphere of radius a we can choose the origin so that has equation x 2 + y 2 + z 2 = a 2 , and so its outward normal is ˆ N = x i + y j + z k a . Thus the flux out of is 1 a ZZ ( F 1 x + F 2 y + F 3 z ) ds = , since the sphere is symmetric about the origin....
