How is the equation for calculating the gravity for inside the earth?
Ie. if there were a hole to the earth's center then
how much would the value of "g" be at point 3/4r, 1/2r, 1/4r ?
Net Force due to gravity is zero at the gravitational center of the
earth--equal force in all directions. Local variations in density
will effect the value gravitation as a function of depth.
