A chain of length L and mass M is held on a frictionless table with `(1//n)th` of its length hanging over the edge. When the chain is released, find the velocity of chain while leaving the table.

Verified by Experts

Work done `Delta W = U_(i) - U_(f) = K_(f) - K_(i)`
`(Mgl)/(2) -(Mgl)/(2n^(2)) = (1)/(2) Mv^(2) , v = sqrt(gl[1 -(1)/(n^(2))])`.
