# Circular Motion #13

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.
