Oscillation motion

Question

A load of mass 'M' is attached to the bottom of a spring of mass 'M/3' and spring constant 'K'. If the system is set into oscillation, the time period of oscillation is

Easy

A

$\large \frac{{2\pi }}{3}\sqrt {\frac{{10M}}{K}}$
B

$\large 4\pi \sqrt {\frac{M}{{3K}}}$
C

$\large 4\pi \sqrt {\frac{M}{K}}$
D

$\large 2\pi \sqrt {\frac{M}{{3K}}}$

Solution

When mass of spring is taken into account
$\large T\, = \,2\pi \sqrt {\frac{{10M}}{{9K}}} \, = \,\frac{{2\pi }}{3}\sqrt {\frac{{10M}}{k}}$
