Question

derive an expression for variation in the acceleration due to gravity with altitude​

Answer 1

Answer:

g = G M R 2 ,

∴ g = G 4 3 π R 3 ρ R 2.

∴ g d = G 4 3 π C P 3 ρ C P 2.

g d g = C P R = R - d R.

Answer 2

Answer:

g = G M R 2 ,

∴ g = G 4 3 π R 3 ρ R 2.

∴ g d = G 4 3 π C P 3 ρ C P 2.

g d g = C P R = R - d R.
