So the difference in\ndistance of the force that is pulling to the one that is pushing\nis only 1 foot out of say 21,120,000 feet to the Earth's pole.\nHence the net force difference is a 21 millionth SQUARED or\n.00000000000004 of the force that you observed on the compass.\n\nOr something like that.\nBob\n\n_______________________________________________\nSent via [email protected].
