Question
Consider a situation in which a ring, a solid cylinder and a solid sphere roll down on the same inclined plane without slipping. Assume that they start rolling from rest and having identical diameter.

The correct statement for this situation is:-

✓

Answer

$a=\frac{g \sin \theta}{1+\frac{I}{m R^{2}}}$

$I_{\text {ring }}\,>\,I_{\text {solid cylinder }}\,>\,I_{\text {solid sphere }}$

$\Rightarrow a_{\text {ring }}\,<\,a_{\text {solidcylinder }}\,>\,a_{\text {solidsphere }}$

$\Rightarrow v_{\text {ring }}\,<\,v_{\text {solid cylinder }}\,<\,v_{\text {solid sphere }}$
