Question

Find the acceleration due to gravity of the moon at a point $1000~km$ above the moon's surface. (Given: mass of the moon is $7.4 	imes 10^{22}~kg$ and its radius is $1740~km$)

Professor PC Thomas Classes · Answer

$g = \frac{GM}{(R+h)^2} = \frac{6.67 	imes 10^{-11} 	imes 7.4 	imes 10^{22}}{((1740 + 1000) 	imes 10^3)^2} = \frac{49.35 	imes 10^{11}}{7.5 	imes 10^{12}} \approx 0.65~m~s^{-2}$.
