A mass of 10 kg is taken up to a distance nine times the Earth's radius above the surface of the Earth.What is its weight in N at that point?

Question

Quizplus · Accepted Answer

The gravitational force decreases with the square of the distance from the center of the Earth. At nine times the Earth's radius above the surface, the total distance from the center is ten times the Earth's radius. The weight is then 1/100th of the weight on the surface, which is 98 N, so the weight is 0.98 N.
