Question

The mass of the earth 6x1024 kg and radius 6.4x106 m.

Calculate the acceleration due to gravity at height of 2000 km

from the surface of the earth​

Answer 1

Explanation:

gh = Gravity at the height 2000 km

g = Gravity at the surface of the Earth

h = 2000 km

r = 6.4 × 10^6

$gh = g(1 - \frac{2h}{r})$

$gh = 9.8(1 - \frac{2 \times 2000}{6400000})$

$gh = 9.8(1 - \frac{1}{1600} )$

$9.8( \frac{1599}{1600} ) = 9.79 \: m {s}^{ - 2}$

Therefore, it is your answer.
