A mass m is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when: |
inclined at an angle of 60° from vertical the mass is at the highest point the wire is horizontal the mass is at the lowest point |
the mass is at the lowest point |
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. |
