A mass is taken to a height R from the surface of earth and then is given horizontal velocity v. The minimum value of v so that mass escapes to infinity is `sqrt((GM)/(nR))`. Find the value of n.

A mass m is taken to a height R from the surface of the earth and then is given a vertical velocity upsilon . Find the minimum value of upsilon , so that mass never returns to the surface of the earth. (Radius of earth is R and mass of the earth m ).

A mass m is taken to a height R from the surface of the earth and then is given a vertical velocity upsilon . Find the minimum value of upsilon , so that mass never returns to the surface of the earth. (Radius of earth is R and mass of the earth m ).

A particle is thrown with escape velocity v_(e) from the surface of earth. Calculate its velocity at height 3 R :-

A particle is thrown with escape velocity v_(e) from the surface of earth. Calculate its velocity at height 3 R :-

A particle is thrown with escape velocity v_(e) from the surface of earth. Calculate its velocity at height 3 R :-

A body is imparted a velocity v from the surface of the earth. If v_(0) is orbital velocity and v_(e) be the escape velocity then for :

The earth is assumed to be a sphere of radius R. A platform is arranged at a height R from the surface of the earth. The escape velocity of a body from this platform is fu, where v is its escape velocity from the surface of the earth the value of f is ..........
