SUMMARY
The magnitude of the attractive force between a satellite and Earth can be calculated using the formula F = GM(sat)M(Earth)/R². In this case, a 1500 kg satellite orbits Earth with a period of 86400 seconds and a radius of 42200000 meters. The correct mass of Earth is 6.0 x 1024 kg, not 6.0 x 107 kg as initially stated. Additionally, the orbital radius must include the Earth's radius to accurately determine the gravitational force.
