Question

Calculate the acceleration due to gravity at a height 300 km from the surface of the earth.​

Answer 1

Answer:

9.8 m/sec square

Explanation:

accelaration due to earth is always constant at certain heights that is 300km is neglected

Answer 2

Answer:

9.01 m/s²

Explanation:

let radius of earth = 7000 km.

g = 9.8 = kM/7000²

g' = kM/7300²

g' /g = 7000²/7300² = (70/73)²

G' = 9.8 (70/73)² = 9.01 m/s²
