A uniform flexible chain of mass m and length 2l hangs in equilibrium over a smooth horizontal pin of negligible diameter. One end of the chain is given a small vertical displacement so that the chain slips over the pin. The speed of chain when it leaves pin is:
- \(\sqrt{2 g \ell}\)
- \(\sqrt{g \ell}\)
- \(\sqrt{4 g \ell}\)
- \(\sqrt{3 g \ell}\)
Answer
(B) g
