Gravitation | Escape Speed

The ratio of the masses and radii of two planets are 4:6 and 8:18 . What is the ratio of the escape speed at their surface ?

Two planets of same density have the ratio of their radii as 1 : 3. The ratio of escape speed on them will be

The ratio of the escape speed from two planets is 3 : 4 and the ratio of their masses is 9 : 16. What is the ratio of their radii ?

Variation in acceleration due to gravity| Gravitational potential energy and Escape velocity

In the above question, escape speed from the centre of earth is :

The gravitational force exerted by the Sun on the Moon is about twice as great as the gravitational force exerted by the earth on the Moon, but still Moon is not escaping from the gravitational influence of the earth. Mark the option which correctly explains the above system.

Let escape velocity od a body a kept surface of a planet is u , If it is projected at a speed of 200 % more than the escape speed , then its speed in interstellar space will be

Escape velocity of a body 1 kg mass on a planet is 100 ms^(-1) . Gravitational potential energy of the body at that planet is

The velocity with which a projectile must be fired so that is escapes earth's gravitation does not depend on:

If a body is thrown at speed of triple as that of escape speed (V_e) from earth s surface, then at what speed it will move in interstellar space?
