If `upsilon_(e)` is the escape velocity for earth when a projectile is fired from the surface of earth. Then, the escape velocity if the same projectile is fired from its centre is

The escape velocity of a projectile from the earth is approximately

The escape velocity of a projectile from the earth is approximately

A projectile is launched from the surface of earth with a velocity less than the escape velocity. Its total mechanical energy is

The escape velocity of a body from the surface of earth is

What is escape velocity? Find an expression for the escape velocity of a body when projected from the surface of the earth. Show that the escape velocity form the earth's surface is about 11.2 km/sec.
