Question

9. Write the formula to find the
magnitude of the gravitational
fore beuneen the carth and an
object on the surface of the earth​

Answer 1

Answer:

1) Let the mass of earth = M.

2) Let the mass of the object = m.

3) Distance between the the earth's centre and object =

4)Radius of the earth = R.

Therefore,

5) Gravitational Force = F = GMm/ R 2

Answer 2

The gravitational force between the earth and an object on the surface of the earth is

F=G Mm/d ^2

Where G = universal gravitational constant

M = the mass of the earth

m= mass of object on the surface of the earth

d= distance between the two bodies
