Question

what is the force of gravity between the Earth and mass of 1kg placed on its surface​

Answer 1

The heavy object when falls, the acceleration due to gravity 'g' is acting which is independent of the mass of the body. Q3. What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? [Mass of the earth is 6 x 1024 kg and radius of the earth is 6.4 x 106 m].

Answer 2

force will be mgh Newton...(9.8N)

m=mass,

g=acceleration due to gravity,

h=height...

hope answer helps you
