Question: A block of mass m is attached to a string and suspended inside a hollow box of mass M. The box rests on a scale

A block of mass m is attached to a string and suspended inside a hollow box of mass M. The box rests on a scale that measures the system's weight.

(a) If the string breaks, does the reading on the scale change? Explain your reasoning.

(b) Assume that the string breaks and mass m falls with constant acceleration g. Find the acceleration of the center of mass, giving both direction and magnitude.
