[1] 0654/61/O/N/12 Q2 A student is investigating forces acting at different angles. He is using the apparatus shown in Fig. 2.1. He hangs a 20g mass, m, half way between the pulleys, at point X. • He places a protractor behind point X so that angle can be measured, as in Fig. 2.2. • θ He measures angle and records it in Table 2.1. • θ He repeats the experiment using masses of 40, 60 and 80g for mass, m. • 2.1 Mass, m/g /° Sine θ θ 0 0 0.00 20 11 0.19 40 22 0.37 60 80 (a) (i) Fig. 2.3 and 2.4 show the angles at point X for the masses m= 60g and m= 80g. For each diagram, read angle and record it in Table 2.1. θ [2]
