A body of mass M kg is on the .top point of a smooth hemisphere of radius 5 m. It is released to slide down the surface of the hemisphere. It leaves the surface when velocity is 5 ms^-1, At this instant the angle made by the radius vector of the body with the vertical is (acceleration due to gravity =10 ms^-2)
