Gravitational Forces, mass and distance

Here the mass of each object remains the same. If the mass doesn't change for either object, the Gravitational Force will remain the same between these two objects.

Here the distance between each object remains the same. If the radius doesn't change between the two objects, the Gravitational Force will remain the same between these two objects.

What would happen to the Gravitational Force if one of the objects increases to twice its mass?

What would happen to the Gravitational Force if the distance between the objects doubled?

What would happen to the Gravitational Force if both objects increased to twice their mass?

What would happen to the Gravitational Force if the distance between the objects came down to half the original distance?

What would happen to the Gravitational Force if one of the objects increases to three times its mass?

What would happen to the Gravitational Force if both the objects got twice as massive and the distance between them increased to twice as far?
