Question: The acceleration of gravity g on a satellite in orbit around Earth varies inversely as the square of its distance r from the center of

The acceleration of gravity g on a satellite in orbit around Earth varies inversely as the square of its distance r from the center of Earth. If g = 8.7 m/s2 for a satellite at an altitude of 400 km above the surface of Earth, find g if it is 1000 km above the surface. The radius of the Earth is 6.4 ×106 m.
