Two bodies of masses m and 4 m are attached to a light string as shown in figure. A body of mass m hanging from string is executing oscillations with angular amplitude 60^∘, while other body is at rest on a horizontal surface. The minimum coefficient of friction between mass 4m and the horizontal surface is (here pulley is light and smooth)
