A particle of mass m starts to slide down from the top of the fixed smooth sphere. What is the tangential acceleration when it break off 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.

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

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

A particle of mass m is released from the top of a smooth hemisphere of radius R with the horizontal speed mu . Calculate the angle with verticle where it loses contact with the hemisphere.

A heavy particle of mass m is in motion on a smooth surface of hemisphere of radius R and there is no friction. At the initial instant the particle is at the topmost point A and has an initial velocity v_(0) At what point will the particle leave the surface of the hemisphere ? Also determine the value of v_(0) for which the particle will leave the sphere at the initial instant.

A particle slides down from the top outside smooth surface of a fixed sphere of radius a=10m . The initial horizontal velocity to be imparted to the particle at the top is 5Km/s ,if it leaves the surface at a point whose vertical height above the centre of sphere is 3a/4. Find the value of K
