The distance between the centres of the Moon and the earth is `D`. The mass of the earth is `81` times the mass of the Moon. At what distance from the centre of the earth, the gravitational force will be zero?

The distance of the centres of moon the earth is D. The mass of earth is 81 times the mass of the moon. At what distance from the centre of the earth, the gravitational force on a particle will be zero.

A rocket is fired from the earth to the moon. The distance between the earth and the moon is r and the mass of the earth is 81 times the mass of the moon. The gravitational force on the rocket will be zero when its distance from the moon is

The point at which the gravitational force acting on any mass is zero due to the earth and the moon system is (The mass of the earth is approximately 81 times the mass of the moon and the distance between the earth and the moon is 3,85,000km ).

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 between the earth and moon were doubled, the gravitational force between them will be
