Upto what maximum height, value of g remains equal to 9.8 or close to it.
- g = GM/r^2
- And g' = GM/(r+h)^2 = g/(1+ h/r)^2
- Therefore when h ≥ r , g' decreases
- Again if h < r , g' agin decreases
- BUT I want to know what is the maximum height at which g' ≈ 9.8
- From my calculation maximum height ≈ 19.3 km, I think I am wrong, so what is the corrrct value of maximum height.
