PhysicsNEET 2019Power and vertical circular motion

Work, Energy and Power

A mass mm is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when:

  1. A.The mass is at the highest point
  2. B.The wire is horizontal
  3. C.The mass is at the lowest point✓
  4. D.Inclined at an angle of 60∘60^\circ from the vertical

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
