If M is the mass of Earth, then the mass of the moon is about `M//80` and the mass of the sun is about 330,000 M. If R is the distance between Earth and the moon, then the distance between Earth and the sun is about 400R. So, which exerts a greater gravitational force on the Earth : the moon or the sun ?

If r is the distance between the Earth and the Sun. Then, angular momentum of the Earth around the sun is proportional to

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

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

What is the moment of the gravitational force of the sun on earth about the axis of its rotation about the sun ?

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
