Oscillations

Question: A mass $M$ is suspended from a light spring. An additional mass $m$ added displaces the spring further by a distance $x$. Now the combined mass will oscillate on the spring with period

1) $T=2\pi \sqrt{\left( mg/x(M+m) \right)}$

2) $T=2\pi \sqrt{\left( (M+m)x/mg \right)}$

3) $T=(\pi /2)\sqrt{\left( mg/x(M+m) \right)}$

4) $T=2\pi \sqrt{\left( (M+m)/mgx \right)}$

Solution:
