#### Question

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

#### Solution

Let *M*_{E} be the mass of the Earth and *m* be the mass of an object on its surface. If *R* is the radius of the Earth, then according to the universal law of gravitation, the gravitational force (*F*) acting between the Earth and the object is given by the relation:-

`F=(Gm_1m_2)/r^2`

Is there an error in this question or solution?
