The distance between two bodies is doubled. How is the magnitude of gravitational force between them affected ?

The separation between two masses is reduced to half. How is the magnitude of gravitational force between them affected ?

If the distance between earth and sun is doubled, they by what factor will the gravitational force between them be changed ?

Frictional force between two bodies

The gravitational force between two bodies is :

If the masses of two bodies are quadrupled and the distance between their centers is doubled, then how many times the force of gravitation between them will be changed ?

If the masses of two bodies are quadrupled and the distance between their centres is doubled, then how many times the force of gravitation between them will be changed ?

How does the distance of separation between two bodies affect the magnitude of the non-contact force between them ?

If the distance between two particles is reduced to half, the gravitational attraction between them will be

Assertion: When distance between bodies is doubled and also mass of each body is also doubled, gravitational force between them remains the same. Reason: According to Neweton's law gravitational, force is directely proportional to mass of bodies and inversely proportional to square of distance between them.
