3 78 A heavy particle of mass m is in motion on a smooth surface of a 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 vo At what point will the particle leave the surface of the hemisphere Also determine the value of vo for which the particle will leave the sphere at the initial instant Ans 0 cos 2 vo 3 3gR gR
