That is where it started, by observing some satellite structures. A barbell shaped object in space will orient radially to a massive body.

Thanks

Got it. At least one of the masses must be a point mass and then only when considering the force exercised on it by a collection of dispersed masses. Then the collection of dispersed masses can be lumped around the center of mass and only for great distances. Thanks

You answered while I was typing Thanks Do not remember exactly, but there was some mention of "spherical symmetry". Now a bar bell O======O does not seem to have spherical symmetry but anything missing to a full sphere could (not really sure) be seen as a collection of bar bell each behaving...

I like math and physics and sometimes I pose myself a question for which I try to get an answer. For a more practical hobby I build model engines Use to design Power Supply and telephone equipment like modems, trunk interfaces and signaling apparatus.

Normalizing respect m, M, R and k then the normalized force for the case of the bar bell body aligned with the direction of R become Fn = 1/(1+x)^2 + (1-x)^2 is a vectorial sum but in this case the vectors are aligned We can assume x<<1 but is not really material to the problem For...
