A block of mass $$M$$ is related from point $$P$$ on a rough inclined plane with inclination angle $$\theta$$, shown in the figure below. The coefficient of friction is $$\mu$$. If $$\mu < \tan \theta$$, then the time taken by the block to reach anorher point $$Q$$ on the inclined plane, where $$PQ=S,$$ is
A
$$\sqrt {{{2s} \over {g\cos \theta \left( {\tan \theta - \mu } \right)}}}$$
B
$$\sqrt {{{2s} \over {g\cos \theta \left( {\tan \theta + \mu } \right)}}}$$
C
$$\sqrt {{{2s} \over {gsin\theta \left( {\tan \theta - \mu } \right)}}}$$
D
$$\sqrt {{{2s} \over {gsin\theta \left( {\tan \theta + \mu } \right)}}}$$
