A small mass m starts from rest and slides down the surface of a frictionless solid sphere of radius R. Calculate the angle at which the mass flies off the sphere. If there is friction between the mass and the sphere, does the mass of fly off at a greater or lesser angle than the previous one ?

1.	A small mass m starts from rest and slides down the surface of a frictionless solid sphere of radius R. Calculate the angle at which the mass flies off the sphere. If there is friction between the mass and the sphere, does the mass of fly off at a greater or lesser angle than the previous one ?
Answer» Solution :`mg cos theta - N=mv^(2)//R, cos theta = V^(2)//RG`. If there is FRICTION, it will fly off at a greater distance
