An object of mass `m` is at rest on earth's surface. Escape speed of this object is `V_(e)`. Same object is orbiting the earth with `h=R`, then escape speed is `V_(e)^(1)`. Then

The total mechanical energy of an object of mass m projected from surface of earth with escape speed is

The total mechanical energy of an object of mass m projected from surface of earth with escape speed is

The escape speed is _________ of mass of the object.

The escape speed for an object from the earth is 11.2 km/s . What is meant by escape speed?

A satellite is orbiting the earth close to its surface. A particle is to be projected from the satellite to just escape from the earth the escape speed from the earth is V_(e) its speed with respect to the satellite

The radius of earth is R and escape speed is v_e . If the radius of earth needs to be changed to nR so that escape speed becomes 10 v_e . Find n
