| To your point. We should have no ambiguity with the far-field effects.
| Might we clear up the matter with the statements?::
| Gravitational force diminishes by 1/r^2 above the earths surface.
| Gravitational force diminishes by 1/r^1 below the earths surface.

I thought that below the surface it fell to zero at the center of the
partical at the center of the earth but still followed a 1/r^2 as far as the
feet of a person in a lift was concerned ?

| <<As the non-bonded interaction between atoms and groups

Coulomb's law has a 1/d^2 dependence and an electric field has 1/r^2
dependence AFAIK so where is the 1/r dependence coming from ?

| Pardon my careless interchange of d distance and r radius.

I thought it made no difference unless you were inside the the point source.
