Question

write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.
​

Answer 1

Answer:

the mass of earth = M.

Let the mass of the object = m.

Distance between the the earth's centre and object = Radius of the earth = R.

Therefore,

Gravitational Force = F = GMm/ R 2

Answer 2

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 = Radius of the earth = R.

4. Therefore,

5. Gravitational Force = F = GMm/ R 2
