A mass m is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when:
Answer & explanation
Correct answer: option 4
the wire is most likely to break where the tension is the most.
T - mg = \(\frac{mu^2}{L}\)
T = mg + \(\frac{mu^2}{L}\)
Tension and mg are in opposite directions at the lowest point.
