Answer:
You swing a ball at the end of string in a vertical circle.
Explanation:
At the top of the circle, the centripetal force on the ball is; larger than its' weight.
- We are told that he swings a ball in a vertical circle at the end of a string that is always in tension. This means that at the top of the circle when the ball is there, it will experience both tension(T) and weight(W) acting towards the center of the circle.
Thus, the net force will be;
F_net = T + W
Where F_net is the centripetal force
- Now, we are told that the string is always taut and this means that the tension in the string can't be zero and as such we can infer that;
Centripetal force which is F_net will be larger than the weight W.
