A small mass slides down a fixed inclined plane of inclination 6 with the horizontal. The coefficient of friction is \[\mu \text{ }=\text{ }{{\mu }_{0}}x\]Where \[x\] is the distance through which the mass slides down and \[{{\mu }_{0}}\] is a constant? Then he speed is maximum after the mass covers a distance of

• A. \[\frac{\cos \theta }{{{\mu }_{0}}}\]
• B. \[\frac{\sin \theta }{{{\mu }_{0}}}\]
• C. \[\frac{tan\theta }{{{\mu }_{0}}}\]
• D. \[\frac{2tan\theta }{{{\mu }_{0}}}\]
