A particle is projected with velocity u horizontally from the top of a smooth sphere of radius a so that it slides down the outside of the sphere. If the particle leaves the sphere when it has fallen a height (a)/(4) , the value of u is

A particle is projected with velocity u horizontally from the top of a smooth sphere of radius a so that it slides down the outside of the spher. If the particle leaves the outsides down th eoutside of the sphere. If the particle leaves the sphere when it has fallen a height (a)/(4) , the value of u is

A particle of mass m slides down from the vertex of semi- hemisphere, without any initial velocity. At what height from horizontal will the particle leave the sphere-

A particle rests on the top of a hemishpere of radius R. Find the smallest horizontal velocity that must be imparted to the particle if it is yo leave the hemisphere without sliding down it.
