Question

3. 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 10 m.)
​

Answer 1

Answer:

gravitational force between the earth and an object is 9.77 N

Answer 2

Answer:

here is the correct answer

Explanation:

Given : Mass of earth M=6×10

24

kg

Mass of object m=1 kg

Radius of earth R=6.4×10
