Questiоn 2: Right Click оn the buttоn to open the imаge in а new tаb. Two particles, A and B, have masses 2 kg and 4 kg respectively. The particles are connected by a light inextensible string. The string passes over a small smooth pulley which is fixed at the top of a rough plane. The plane is inclined to the horizontal ground at an angle α where tan α = . The particle A is held at rest on the plane at a distance d meters from the pulley. The particle B hangs freely at rest, vertically below the pulley, at a distance h meters above the ground, as shown in the Figure. The part of the string between A and the pulley is parallel to a line of greatest slope of the plane. The coefficient of friction between A and the plane is . The system is released from rest with the string taut and B descends. a Find the tension in the string as B descends. (9) On hitting the ground, B immediately comes to rest. Given that A comes to rest before reaching the pulley, b find, in terms of h, the range of possible values of d. (7) [16]
