Determine the ratio of Earth's gravitational force exerted on an 80-kg person when at Earth's surface and when 1000 km above Earth's surface. The radius of Earth is 6370 km.
The force exert on the person having mass m =80 kg
On the surface of the earth is F1
Me = mass of the earth
Now when person is at h=1000 km above the surface of the earth then force exert on person is F2
Now ratio of F1 /F2
This is the ratio of forces .
R= radius of the earth
