A heavy uniform chain lies on horizantal table top. If the coefficient of friction between the chain and the table surface is 0.5 , the maximum percentage of the length of the chain that can hang over one edge of the table is

A uniform chain of length L is lying partly on a table, the remaining part hanging down from the edge of the table. If the coefficient of friction between the chain and the table is 0.5 what is the minimum length of the chain that should lie on the table, to prevent the chain from slipping down to the ground.
