1Å A B 1 m 2.4 kg 3.3 kg Particles A and B, of masses 2.4kg and 3.3kg respectively, are connected by a light inextensible string that passes over a smooth pulley which is fixed to the top of a rough plane. The plane makes an angle of 1Å with horizontal ground. Particle A is on the plane and the section of the string between A and the pulley is parallel to a line of greatest slope of the plane. Particle B hangs vertically below the pulley and is 1m above the ground (see diagram). The coefficient of friction between the plane and A is -.
