Joe has a weight of 850 N (about 193 lb) when he is standing on the surface of the Earth. What would his weight (the gravitational force due to the Earth) be if he tripled his distance from the center of the Earth by flying in a spacecraft?

Take the weight and divide it by 9.
850N/(3r)^2= 850/9r^2=94.4 Newtons
