The value of escape velocity of a certain planet is `sqrt(2)km/s` .Then the value of orbital speed for a satellite orbiting closer to its surface is ?

The value of escape velocity on a certain planet is 2 km/s. Then the value of orbital speed for a satellite orbiting close to its surface is

The value of escape speed from certain planet is 4 km/s. What will be the orbital speed of a satellite orbiting close to its surface ?

A satellite orbiting close to earth surface will escape, if

The orbital velocity of a planet revolving close to earth's surface is

The escape velocity of a satellite from the surface of a planet is sqrt(2) times the orbital velocity of the satellite. If the ratio of the masses of two given planets is 1 : 4 and that of their radii is 1 : 2, respectively, then find the ratio of escape velocities of a satellite from the surfaces of two planets.

The escape velocity of a body from the surface of the earth is 11.2 km/s. If a satellite were to orbit close to the surface, what would be its critical velocity ?

The escape velocity for a planet is 20 km//s . Find the potential energy of a particle of mss 1 kg on the surface of this planet.

Consider a hypothetical planet which is very long and cylinderical. The density of the planet is rho , its radius is R . What is the possible orbital speed of the satellite in moving around the planet in circular orbit in a plane which is perpendicular to the axis of planet?
