Comprehension \( \quad \) A fixed wedge with both surface inclined at \( 45^{\circ} \) to the horizontal as shown in the figure. A particle \( P \) of mass \( m \) is held on the smooth plane by a light string which passes over a smooth pulley \( A \) and attached to a particle \( Q \) of mass \( 3 \mathrm{~m} \) which rests on the rough plane. The system is released from rest. Given that the acceleration of each particle is of magnitude \( \frac{g}{5 \sqrt{2}} \) then

In the above question the coefficient of friction between \( Q \) and the rough plane is:
(a) \( \frac{4}{5} \)
(b) \( \frac{1}{5} \)
(c) \( \frac{3}{5} \)
(d) \( \frac{2}{5} \)
