On the upper edge of an inclined plane with an angle of inclination to the horizon a = 60° there is a block through which a thread is thrown (Fig.). At the end of the thread hanging from the block, a mass of mass m1 = 240 g is attached, with the help of which two masses of mass m2 = m3 = 100 g, attached to the other end of the thread, are lifted along an inclined plane with an acceleration of a = 0.1 g, connected to each other by a thread. Find the coefficient of friction between the surface of the inclined plane and the loads and the tension force of the rope connecting the lifted loads. Neglect the mass of the block and thread, as well as the friction in the axis of the block.
