It varies directly with the masses, say M₁, M₂ and inversely with the square of distance between two objects, say r.

where G is called the ‘gravitational constant’ or ‘constant of gravity’.

Mass of earth = 5.98 x 10 kg

Since the object is on the surface of the Earth, the distance between the Earth and the object is the radius of the earth,
