A planet has the radius twice that of earth and has same density as that of earth. If `V_(p)andV_(e)` are the escape velocities for the planet and earth, then which of the following correct relation is:

A planet has twice the radius but the mean density is 1/4 th as compared to earth. What is the ratio of escape velocity from earth to that from the planet

If mass of planet is eight times the mass of the earth and its radius is twice the radius of the earth, what will be the escape velocity for that planet?

The radius of a planet is double than that of the earth but their average densities are the same. If the escape velocities of the planet and the earth are v_p and v_e respectively, then prove that v_p=2v_e .

A planet has a mass 120 times that of earth and radius is 5 times the radius of earth. What is the escape velocity at this planet if the escape velocity at earth's surface is 11.2 km s^(-1) .

The escape velocity of a body from the earth is V_(e) . The escape velocity of a planet whose mass and radius are twice those of the earth is

The mass of a planet is six times that of the earth. The radius of the planet is twice that of the earth. It's the escape velocity from the earth is v , then the escape velocity from the planet is:

The mass of a planet is six times that of the earth. The radius of the planet is twice that of the earth. If the escape velocity from the earth is v , then the escape velocity from the planet is:

The escape velocity from the earth is V. What is the escape velocity from a planet whose mass and radius is twice those of the earth ?
