A solid cylinder of mass \( M \) and radius \( \mathrm{R} \) rolls without slipping down an inclined plane of length \( L \) and height
\( \mathrm{h} \). What is the speed of its centre of mass when the cylinder reaches its bottom :-
(1) \( \sqrt{2 \mathrm{gh}} \)
(2) \( \sqrt{\frac{3}{4} g h} \)
(3) \( \sqrt{\frac{4}{3} g h} \)
(4) \( \sqrt{4 g h} \)
\( \mathrm{P} \)
