Acceleration due to gravity is $g$ on the surface of the earth. Then the value of the acceleration due to gravity at a height of $32 km$ above the earth's surface is (Assume the radius of the earth to be $6400 km$ )

Options:

Answer:

Solution:

Acceleration due to gravity at height $h$ is

$g^{'} = \frac{g}{{(1 + \frac{h}{R_{e}})}^{2}} = \frac{g}{{(1 + \frac{32}{6400})}^{2}} = 0.99 g$
