In the arrangement shown in figure, there is friction between the blocks of masses m and 2m which are in contact. The ground is smooth. The mass of the suspended block is m. The block of mass m which is kept on mass 2m is stationary with respect to block of mass 2m. The force of friction between m and 2m is (pulleys and strings are light and frictionless) : 1) 2) 3) 4)
