hey can smone plz help me with this...

Figure 3 ( attachment) shows a particle X of mass 3 kg on a smooth plane inclined at an angle 30° to the
horizontal, and a particle Y of mass 2 kg on a smooth plane inclined at an angle 60° to the
horizontal. The two particles are connected by a light, inextensible string of length 2.5 metre
passing over a smooth pulley at C which is the highest point of the two planes.
Initially, Y is at a point just below C touching the pulley with the string taut. When the
particles are released from rest they travel along the lines of greatest slope, AC in the case of
X and BC in the case of Y, of their respective planes. A and B are the points where the planes
meet the horizontal ground and AB = 4 metres.

initial acceleration of the system is given by : g/10(2x3^0.5 -3)

    By finding the tension in the string, or otherwise, find the magnitude of the force
exerted on the pulley and the angle that this force makes with the vertical.


thanks,,

Amr Fouad:
please post original question..i cudnt figure out whether the multiplied part of acceleration is with the num or denom
