A ring takes time \( t_{1} \) and \( t_{2} \) for sliding down and rolling down an inclined plane of length \( \mathrm{L} \) respectively for reaching the bottom. The ratio of \( \mathrm{t}_{1} \) and \( \mathrm{t}_{2} \) is :-
(1) \( \sqrt{2}: 1 \)
(2) \( 1: \sqrt{2} \)
(3) \( 1: 2 \)
(4) \( 2: 1 \)
\( \mathrm{P} \)
