2 6091/2/09/22 Section A [70 marks] Answer all questions in the spaces provided. 1 (a) (i) State the difference between scalar and vector quantities. [1] (ii) Force is a vector quantity. State an example of a scalar quantity. [1] (b) Fig. 1.1 shows three weights, X, Y and Z attached to three strings that are joined at P. The strings attached to X and Z are on frictionless pulleys. The weight of Y is 4 N and the weights of X and Z are equal. In the position shown, all three weights are at rest. Fig. 1.1 In the space below, draw a labelled diagram to determine the tension in the string attached to X. tension in string attached to X = ………………………….. [3] [Total: 5] pulley X Y Z P 100°
