A uniform flexible chain of mass \( m \) and length \( l \) hangs in equilibrium over a smooth horizontal pin of negligible diameter. One end of the chain is given a small vertical displacement so that
P the chain slips over the pin. The speed of chain when it leaves pin is

W
(a) \( \sqrt{\frac{g l}{2}} \)
(b) \( \sqrt{g l} \)
(c) \( \sqrt{2 g l} \)
(d) \( \sqrt{3 g l} \)
