What happens to the force between two objects, if the distance between the objects is doubled and tripled?
Choose the correct alternative:
Acceleration due to gravity is independent of mass of the earth/mass of the body.
How will you ‘weigh the sun’, that is estimate its mass? The mean orbital radius of the earth around the sun is 1.5 × 108 km.
How does the force of gravitation between two objects change when the distance between them is reduced to half?
What is the magnitude of the gravitational force between the earth and a 1 kg object on its surface? (Mass of the earth is 6 × 1024 kg and radius of the earth is 6.4 × 106 m).
