Circular Motion #13

Classical Mechanics Level 3

A small bob with mass \( m \) hangs from a light string which is fixed at the other end. The bob is held in such a way that the string is horizontal and without any slack. The bob is released from rest from this point. If the string has a breaking-point force of \( 12 \text{ N} \), what is the maximum value of \(m\) (in kg) so that the string does not break at any point during the motion?

  • Take \( g = 10 \text{ m s}^{-2} \)
  • Neglect air resistance.
