Q P 2.75 m α 0.3 kg 0.6 kg Particles P and Q have masses 0.3 kg and 0.6 kg respectively. The particles are held at rest at a distance of 2.75 m apart on a line of greatest slope of a rough plane inclined at angle a to the horizontal, where . sin 0 28 a = (see diagram). The coefficient of friction between each particle and the plane is 0.5. Particles P and Q are then released.
