Amplitude of string when the string breaks

[desmond iking]

Homework Statement

my question is on part b

Homework Equations

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.

True.

Not true.

True.


Not true.

why the third statement is not true? i can't unbderstand
