A body of mass \( m \) slides down an incline and reaches the bottom with a velocity \( v \). If
\( \mathrm{P} \) the same mass were in the form of a ring

W which rolls down this incline, the velocity of the ring at the bottom would have been
(1) \( v \)
(2) \( v \sqrt{2} \)
(3) \( \frac{v}{\sqrt{2}} \)
(4) \( \left(\sqrt{\frac{2}{5}}\right) v \)
