A B 2 kg 3 kg P Q 10Å 20Å As shown in the diagram, particles A and B of masses 2 kg and 3 kg respectively are attached to the ends of a light inextensible string. The string passes over a small fixed smooth pulley which is attached to the top of two inclined planes. Particle A is on plane P, which is inclined at an angle of 10Å to the horizontal. Particle B is on plane Q, which is inclined at an angle of 20Å to the horizontal. The string is taut, and the two parts of the string are parallel to lines of greatest slope of their respective planes.
