A uniform chain of length 2L is hanging in equilibrium position, if end B is given a slightly downward displacementthe imbalance causes an acceleration. Here pulley is small and smooth & string is inextensibleThe velocity v of the string when it slips out of the pulley (height of pulley from floor > 2L)(A) √(gL/2)(B) √(2gL)(C) √(gL) (D) none of these
