Question

An astronaunt weighs 8.00x10^2 newtons on the surface of Earth. What is the weight of the astronaut 6.36x10^6 meters above the surface of Earth?

Answer 1

Since g = GM/(R+r)^2 where R earth's radius which measures 6.36 * 10 ^ 6 m
M is mass of the earth and G is universal gravitational constant.
Also r is distance of the object from the surface of the earth.
At surface of the earth r = 0
So g = GM/R^2
Now calculate g' at r = 6.36*10^2 = R
weight = mg
Hope this helps
