Two asteroids, one with a mass of and the other with mass , are apart. What is the gravitational force on the LARGER asteroid?

An astronaut lands on a planet with twelve times the mass of Earth and the same radius. What will be the acceleration due to gravity on this planet, in terms of the acceleration due to gravity on Earth?

An asteroid with a mass of approaches the Earth. If they are apart, what is the gravitational force exerted by the asteroid on the Earth?

Two satellites are a distance from each other in space. If one of the satellites has a mass of and the other has a mass of , which one will have the greater acceleration?

Two planets are apart. If the first planet has a mass of and the second has a mass of , what is the gravitational force between them?

A satellite orbits above the Earth. What is the tangential velocity of the satellite?

An astronaut lands on a planet with twice the mass of Earth, and half of the radius. What will be the acceleration due to gravity on this planet, in terms of the acceleration due to gravity on Earth?
