Particles P and Q, of masses 4kg and 6 kg respectively, are attached to the ends of a light inextensible string. The string passes over a smooth fixed pulley. The system is in equilibrium with P hanging 1.75 m above a horizontal plane and Q resting on the plane. Both parts of the string below the pulley are vertical (see diagram). (a) Find the magnitude of the normal reaction force acting on Q. [1] 1.75 m P Particles P and Q, of masses 4kg and 6 kg respectively, are attached to the ends of a light inextensible string.
