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

Explanation

Mass of the Earth `=M_(E)`
Mass of an object on its surface =m
Radius of the Earth =R
Accoding to the universal law of gravitational force (F) acting between the Earth and the oject is given by the relation :
`F=Gm_(1)m_(2)//r^(2)`
Thus , the formula will be , `F=GM_(E)m//R^(2)`
