Solution Preview

The gravity field of a mass M at a distance r from its center, is:
(1) g= G M / r^2.
STEP 1. It is obvious that at the center of the spherical shell, the gravity field of any surface mass element is exactly canceled by an equal mass element diametrically opposite so all elements of the field are canceled.
For a point not at the center, attachment #1 shows two opposite surface elements of mass ...
