Answer:
Mass and distance between them are two factors on which force of gravity depends
Explanation:
According to law of gravitation
Gravitational force between two object is given by
, here G is gravitational constant
are mass of the objects and r is distance between them
From the relation we can see that force of gravity is dependent on the mass of the objects and distance between them.
So mass and distance between them are two factors on which force of gravity depends
