A light rigid wire of length 1 m is attached to a ball A of mass 500 g to one end. The other end of the wire is fixed, so that the wire can rotate freely in vertical plane about its fixed end. At the lowest point of the circular motion, the ball is given a horizontal velocity 6 m/s. Determine the radial component of the acceleration of the ball, when this rigid wire makes an angle 60° with the upward vertical. (Assume g = 10 m/s2)
