The acceleration due to gravity at height h above the earth if h R (Radius of earth) is given by (a) g' = g(1 - 2h/R) (b) g' = g(1 - (2h²)/(R²)) (c) g' = g(1 - (h²)/(2R²)) (d) g' = g(1 - h/2R)

Answer: (a). g' = g(R/R+h)² = g(1+h/R)⁻² For h R, binomial approximation: (1+x)⁻² ≈ 1-2x g' = g(1-2h/R) So the answer is (a).
