Consider a planet in some solar system which has a mass double the mass of the earth and density equal to the average density of the earth. An object weighing W on the earth will weigh

Calculate the average density of Earth.

A planet has double the mass and double the average density of the earth. If the weight of an object on the earth is 100 N, its weight on the planet will be

A planet has a mass of eight time the mass of earth and denisity is also equal to eight times a the average density of the earth. If g be the acceleration due to earth's gravity on its surface, then acceleration due to gravity on planet's surface will be

A planet has a mass of eight time the mass of earth and denisity is also equal to eight times a the average density of the earth. If g be the acceleration due to earth's gravity on its surface, then acceleration due to gravity on planet's surface will be

Mass And Density On Earth

A planet has mass equal to mass of the earth but radius one fourth of radius of the earth . Then escape velocity at the surface of this planet will be

A planet has mass equal to mass of the earth but radius one fourth of radius of the earth . Then escape velocity at the surface of this planet will be

The planet Egabbac (in another solar system) has a radius twice that of the earth's but an average mass density which is the same as the earth. Would the weight of an object on Egabbac's surface to be the same as on the earth's greater than on the earth's or less than on the earth's ? If greater or less than on the earth's then by how much?
