A body of mass m is Whirled in a vertical circle by means of a rope. If the speed of the body at the highest and lowest points are u and 4u respectively,prove that the tension in the rope when its inclination to the downward vertical is (theta) is approximately mg(3cos theta +2.27). If the length of the rope is 30cm and theta is 45° find the speed of the body at that position.
