Answer to Question #306955 in Mechanics | Relativity for Aria

Question

From the known mass and radius of the moon, compute the value of the acceleration due to gravity, gM at the surface of the moon.

(mass of the moon M = 7.35 X10²² kg) ( G = 6.67 X10⁻¹¹ Nm²/kg² )

(radius of the moon R = 1.7374 X10⁶ )

Answer 1

Answer

the value of the acceleration due to gravity

$g=\frac{GM}{R^2}\\=\frac{6.67*10^{-11}*7.35*10^{22}}{(64*10^5)^2}\\=0.126m/s^2$
