As per your syllabus, eqn 7.15, for SMALL height h (h ≪ R_E) above Earth, the variation of g with h is approximately which?
Ag(h) ≈ g (1 − 2h/R_E)
Bg(h) ≈ g (1 − h/R_E)
Cg(h) ≈ g (1 + 2h/R_E)
Dg(h) ≈ g (1 + h/R_E)
Answer & Solution
Correct answer: A. g(h) ≈ g (1 − 2h/R_E)
syllabus eqn 7.15: g(h) = g/(1+h/R)² ≈ g(1 − 2h/R) for h ≪ R. Decreases linearly.
