A lead fishing weight of mass 0.2 kg is tied to a fishing line that is 0.5 m long. The weight is then whirled in a vertical circle. The fishing line will break if its tension exceeds 80 N .

Part A
If the weight is whirled at higher and higher speeds, at what point in the vertical circle will the string break (top, bottom, or random position)?
Part B
At what speed will the string break?
