Expert Solution
Introduction:
The ball goes in circular motion. We know that whenever there is circular motion, a centripetal force acts towards the center. This centripetal force is provided by the horizontal component of tension. The vertical component of tension balances the weight. We first find the tension. We then equate this to centripetal force to find speed.
