An object slides down a smooth incline and
\( \mathrm{P} \)
reaches the bottom with velocity \( v \). If same mass is in the form of a ring and its rolls down an
W
inclined plane of same height and angle of inclination, then its velocity at the bottom of inclined plane will be
(1) \( v \)
(2) \( \frac{v}{\sqrt{2}} \)
(3) \( 2 v \)
(4) \( \sqrt{2} v \)
