Question

What will be the gravitational force between earth and an object of 1 kg. placed on its surface
Here, the mass of earth is6×10^24kg, and distance from the earth to the earth's surface is 6400 km​

Answer 1

Answer:

We know gravitation force F=R2GMm=(6.4×106)26.67×10−11×6×1024×1

=9.8N 

Where M = mass of the earth, m = mass of the object and R = radius of earth

Explanation:

hope it helps..

Answer 2

Answer:

9.8 N

Explanation:

because, gravitational force = 9.8 N

therefore, 1×9.8 N =9.8 N
