Question

A solid disc of radius ' $a$ ' and mass ' $m$ ' rolls down without slipping on an inclined plane making an angle $	heta$ with the horizontal. The acceleration of the disc will be $\frac{2}{b} g \sin 	heta$, where $b$ is\ $\qquad$ -\ (Round off to nearest integer)\ ( $g=$ acceleration due to gravity, $	heta=$ angles as shown in figure)\
