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

Options:

Answer:

Solution:

$a = \frac{g s i n θ}{(1 + \frac{I}{m R^{2}})}$
$I_{ring} > I_{solidcylinder} > I_{solidsphere}$
$\Rightarrow a_{ring} < a_{solidcylinder} < a_{solidsphere}$
$\Rightarrow v_{ring} < v_{solidcylinder} < v_{solidsphere}$
