The force attracting a piont mass to the center of the earth is affected by the mass and the separating distance.
The law of universal gravitation states that a point mass is attracted to other points mass, the effect on the force is directly proportional to the product of the mass and inversely proportional to the separating distance.
The expression of the Gravitational Force is given as
[tex]F = \frac{Gm1 m2 }{d^{2} }[/tex]
F = force
G = gravitational constant
m1 = mass of object 1
m2 = mass of object 2
d = distance between centers of the masses
