2) A mass $m$ hangs from a massless spring connected to the roof of a box of mass $M$. When the box is held stationary, the mass–spring system oscillates vertically with angular frequency $\omega$. If the box is dropped and falls freely under gravity, how will the angular frequency change?

A) $\omega$ will be unchanged
B) $\omega$ will increase
C) $\omega$ will decrease
D) Oscillations are impossible under these conditions.
E) $\omega$ will either increase or decrease depending on the values of $M$ and $m$.
