Question
A satellite orbits the earth at a distance of 15,000 miles away from the Earth's center. At this distance the force of gravity on the satellite is 90 lbs. At what distance from the Earth's center would the force on the same satellite be 10 lbs?
Answers
1/9 the force, so 3 times the distance: 45,000 miles
