Question

calculate the acceleration due to gravity at a height of 30p km from the surface of the earth.(M=5.99x10^24 kg, R=6400 km)
[Ans=8.889m/s²]​

Answer 1

Explanation:

g = GM / (R + h)^ 2

$g = 6.67 \times {10}^{ - 11} \times 5.99 \times {10}^{24} \div (6.4 \times {10}^{6} + 30 \times {10}^{3} ) ^{2}$

g = 8.889 m/ s^2
