Question

The mass of the moon is 7.2*10^22 kg and it's radius is 1.7*10^6 m.calculate the acceleration due to gravity of the moon and also calculate the wight of an object of mass 50kg on the lunar surface.​

Answer 1

Answer:

On the surface of the moon, the distance to the center of mass is the same as the radius: r=1.74×10
