71Few motion equation from Newton's laws and Energy Conservation would do the work. Set N = 0 and get v from Energy Conservation (Height being already given)
A particle slides from the top down the outside smooth surface of a fixed sphere of radius 'R'. When the particle is at its highest position, what velocity in the horizontal direction should be imparted to it , so that it leaves the surface of a sphere at a point whose vertical height from the centre of the sphere is 4R/5.
