If the mass of earth were `4` times the present mass, the mass of the moon were half the present mass and the moon were revolving around the earth at twice the present distance, the time period of revolution of the moon would be (Indays)

If the mass of earth were 2 times the present mass, the mass of the moon were half the present mass and the moon were revolving round the earth at the same present distance, the time period of revolution of the moon would be (in day)

If the mass of a body on the earth’s surface is M, then its mass on the moon will be--------.

The mass of the earth is 81 times the mass of the Moon and the distance between the earth and the Moon is 60 time the, radius of the earth. If R is the radius of the earth, then the distance between the Moon and the point on the in joining the Moon and the earth where the gravitational force becomes zero is

If the distance of the moon from earth is and the period of revolution is T_(m) ,then the mass of the earth is

The mass of the moon is about 1.2% of the mass of the earth. Compared to the gravitational force the earth exerts on the moon, the gravitational force the moon exerts on earth
