Let the density of chain is d and the length of chain is 3L then L is the lengthwhich is hanging from the table so force of gravity on this part=Ldgremaining mass of chain=d·2Lso frictional force on this part=μd·2LgWhen chain starts sliding the force of gravity is just enough to overcome tstatic friction force μd·2Lg=Ldgμ=0.5
