Textbook Question
Textbook Question(III) The value of g is altered by approximately
∆g ≈ -2g ∆r/r_E
at a height ∆r above the Earth’s surface, where r_E is the radius of the Earth, as long as ∆r ≪ r_E .
(c) Use this result to compute the effective value of g at 125 km above the Earth’s surface. Compare to a direct use of Eq. 6–1.
