2 EFSS/PRELIM-2024/SEC 4 PHYSICS (6091)/Paper 2/YAC SECTION A Answer all the questions in the spaces provided. 1 A set of traffic lights hangs from the end of a metal cable. A horizontal chain pulls the traffic lights to the right so that they are above the middle of the road. Fig. 1.1 shows the metal cable inclined to the vertical. Fig. 1.1 The weight of the traffic lights is 240 N. (a) Two of the forces on the traffic lights are the tension in the horizontal chain and the weight of the traffic lights. On Fig. 1.1, mark and label the two forces using arrows. [1] (b) The tension in the horizontal chain is 140 N. In the space below, use a scale diagram to determine the size and direction of the resultant of the weight and the tension in the chain. State the scale used for the diagram. scale = ........................................ size of resultant force = ........................................ direction of resultant force = ....................................
