Amplitude of string when the string breaks

  1. Jun 24, 2014 #1
    1. The problem statement, all variables and given/known data

    my question is on part b

    2. Relevant equations

    3. The attempt at a solution

    the period will be shorter due to smaller mass of oscillating system... but the amplitude is greater( ans from my book , in my opinion, the amplitude should be smaller because the string is (dispalcement) is displaced lesser if the mass is removed

    By the time the string breaks the metal strip is already deflected downwards to its maximum deflection so your reasoning makes no sense. The strip will oscillate around the new equilibrium position which is further up since the mass is removed. That means the extreme position is further away from the equilibrium position increasing the amplitude.
