Question

A solid cylinder is placed gently over an incline plane of inclination $60°$. The acceleration of cylinder when it start rolling without slipping is $\frac{g}{\sqrt x}$ where $μ$ is the coefficient of friction. [take $g$ = $10\;m / (s ^ 2)$ ]

Answer 1

$Acceleration \;of \;cylinder$:

$a=\frac{g\frac{\sqrt3}{2}}{\frac{3}{2}}$

$=\frac{g}{\sqrt3}$

The Correct Answer is : $\frac{g}{\sqrt3}$
