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

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

Let 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:

F = GMm/R².

Explanation:

Let 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,

F= GMm/R².
