MCQ Solution:
Two satellites A and B of the same mass are going around earth in concentric orbits. The distance of satellite B from Earth’s center is twice that of satellite A What is the ratio of the centripetal force acting on B to that acting on A?
1. 1/8 2. ¼
3. ½ 4. 1/
Ö2The centripetal force is provided by the gravitational force between the satellite and the earth, which goes like 1/r2. When we double the distance we decrease the force by ¼.
