Gravitational force does not depend on:
The gravitational constant.
Charge on two bodies
Separation between two bodies.
Masses of two bodies.
The Gravitational force between two bodies does not depend on the charge of two bodies.
It is F = Gm1m2/R2.
The force of gravitation between two bodies in the universe does not depend on:
If the mass of one body is doubled, then the gravitational force F between two bodies become
