One end of a spring of force constant $k$ is fixed to a support $S$ on an inclined plane of angle $\theta$ and the other end is connected to a block of mass $m$ as shown in the following figure.
The inclined plane is smooth. If the block is displaced along the through a small distance and released, the mass executes simple harmonic oscillations. The period of oscillations is:
