Question

find the gravitational force between a moon of mass a 60kg and car of maas 1600kg separated by 16 m.​

Answer 1

Answer:

Acceleration due to gravity on the moon is 1/6 times as that on the earth and we know that mass is property of the material it always remains same and weight is measure of gravitational force, hence

mass of object on moon is 60kg and weight =60g/6=10×10=100N

Answer 2

Answer:

Explanation:

Given that,

Mass of the Earth m

​

=6×10

24

kg

Mass of the Moon m

2

​

=7.4×10

kg

Distance between the Earth and the Moon d=3.84×10
