Question

What is the acceleration due to gravity at the Moon’s surface? Moon’s mass = 7.35 x 1022 kg, the radius of the Moon is 1.7 x 106 m, universal gravitational constant is 6.67 x 10-11 N m2 / kg2.

I will mark branlist and give high rating who ever gives me the correct answer ​

Answer 1

Answer:

g=1.63\ m/s^2g=1.63 m/s 2

Acceleration due to gravity on the surface of the moon is 1.620 m/s2.

On the surface of the moon, the distance to the center of mass is the same as the radius: r=1.74×106m=17,40,000 m. The acceleration due to gravity on the surface of the moon can be found using the formula:

g=GM/r²

g= (6.673×10−11)(7.4×1022)/17400000

The acceleration due to gravity on the surface of the moon is 1.620 ms2.
