The ratio of the acceleration for a solid sphere (mass $‘ m'$ and radius $R)$ rolling down an incline of angle $‘ θ'$ without slipping and slipping down the incline without rolling is:NEET 2014

Options:

Answer:

Solution:

$a_{1} = \frac{g \sin θ}{1 + \frac{I}{M R^{2}}}$
$a_{2} = \frac{g \sin θ}{1 + \frac{\frac{2}{5} M R^{2}}{M R^{2}}} = \frac{5}{7} g \sin θ$
$\frac{a_{1}}{a_{2}} = \frac{5}{7}$
