6. The diagram shows a particle P of mass M kg suspended from two strings. The strings pass over smooth pulleys A and B and attach to hanging particles. The masses of particles below A and B are 2 kg and 3 kg respectively. The strings to A and B make angles of 30 and as" to the horizontal as shown in the diagram. A (a) Calculate the value of a .
