A sphere of mass $M$ and radius $R$ is released from the top of an inclined plane of inclination $θ .$ The minimum coefficient of friction between the plane and the sphere so that it rolls down the plane without sliding is given by

Options:

Answer:

Solution:

$μ \geq \frac{\tan θ}{1 + \frac{R^{2}}{K^{2}}}$

$\Rightarrow μ_{\min} = \frac{\tan θ}{1 + \frac{R^{2}}{K^{2}}}$
