A small block of mass m has speed sqrt(gR) /2 at the top most point of a fixed hemisphere of radius R as shown in figure. The angle theta , when block loses the contact with the hemisphere is

A small block of mass M moves on a frictionless surface of an inclined plane, as shown in the figure. The angle of the incline suddenly changes from 60^(@) to 30^(@) at point B . The block is many at rest at A . Assume that collisions between the block id the incline are totally inelastic. The speed of the block at point C , immediately before it leaves the second incline
