The distance between Joe and Patti is equal to one meter. At the same the same time the planet Mars which has a mass of 6.0*10^23 kg is located at a distance of 3.0*10^11 meters from Earth. If the masses of Patti and Joe are 50kg and 90kg respectively calculate the ratio of the gravitational force exerted on Joe by Patti with that exerted on Joe by the planet Mars. From the results if anything what can you say about the idea that the supposed astrological influences are gravitational in nature?
