Help with M1 dynamics question.

Please can you help me solve the following question:

Two particles P and Q of equal mass are connected by a light inextensible string. The string passes over a small smooth pulley which is fixed at the top of a fixed wedge. One face of the wedge is smooth and inclined to the horizontal at an angle of 30 degrees. The other face of the wedge is rough and inclined to the horizontal at an angle of 60 degrees. Particle P lies on the rough face and particle Q lies on the smooth face with the string connecting them taut. The coefficient of friction between P and the rough face is 0.5.

find a) the acceleration b) the tension in the string.
