Question

calculate the mass and radius of moon​

Answer 1

Answer:

The mass and radius of moon are 7.4×10

22

kg and 17.4×10

6

kg .

Answer 2

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

6

m=17,40,000 m. The acceleration due to gravity on the surface of the moon can be found using the formula:

g=

r

GM

g= 17400000(6.673×10 −11 )(7.4×10 22 )

The acceleration due to gravity on the surface of the moon is 1.620 ms
