Question

A uniform chain has a mass $M$ and length $L.$ It is placed on a frictionless table with length $l_0$ hanging over the edge. The chain beings to slide down. Then the speed $V$ with which the end slides away from the edge is given by :

• A. $V=\sqrt{\frac{g}{L}(L+l_o)}$
• B. $V=\sqrt{\frac{g}{L}(L-l_o)}$
• C. $V=\sqrt{\frac{g}{L}(L^2-l_o^2)}$
• D. $V=\sqrt{2g(L-l_o)}$

Answer 1

The correct option is C $V=\sqrt{\frac{g}{L}(L^2-l_o^2)}$
