Question

calculate the value of acceleration due to gravity on moon's surface given mass of moon =7.4×10^22kg of radius 1750km?
​

Answer 1

Explanation:

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= r2

r
