In one hand you hold a 0.13-kg apple, in the other hand a 0.23-kg orange. The apple and orange are separated by 1.25 m. What is the magnitude of the force of gravity in the following situations?
Your friends respond that they thought gravity was just a lot weaker up there. Convince them and yourself that it isn't so by calculating the acceleration of gravity 575 km above the Earth's surface in terms of g. (One g is, of course, 9.8 m/s2.)
