A body of mass \( m \) slides down an incline and reaches the bottom with a velocity \( \mathrm{v} \). If the same mass were in the form of a ring which rolls down this incline, the velocity of the ring at the bottom would have been
(1) \( \mathrm{v} \)
(2) \( v \sqrt{2} \)
(3) \( \frac{v}{\sqrt{2}} \)
(4) \( \left(\sqrt{\frac{2}{5}}\right) \mathrm{v} \)
\( \mathrm{P} \)
