A small spherical marble of mass m and radius r is rolling without slipping on a rough track with speed v.The track further is in the shape of a vertical circle of radius R as shown in figure-5.144. With what minimum linear speed the marble is rolling so that it completely goes round the circle on the circular part of track.
