A particle of mass m is tied to one end of the rope, while the other end of the rope is tied to the upper end of a rod placed vertically above a block with mass M = 2 Kg which is resting on the floor with a static friction coefficient H₁ = 0.5. The particles are then stretched in a horizontal position as shown below and released from rest. Calculate the maximum mass of the particles so that the block remains stationary during the movement of the particles!
