Author(s) of paper(s) chosen for publication: [Kathryn Turner]
Comments: there seemed to be more difficulty with this problem than usual,
probably because the answer was not on the web already. Only half the
papers were correct; the quantity of papers indicated that people thought
this was an easy problem but were unable to solve it correctly. Several
of the papers seemed very confused using spherical coordinates.
INSTRUCTOR'S COMMENT: Almost everybody tried to use Gauss's theorem
without completing the surface to a CLOSED one. That can be done, but
it is simpler to do the surface integral directly by the parametric method
(in spherical coordinates). Kathryn's paper has some minor typos, but at
this late date they can be ignored.
