pearson edexcel gce question booklet and mark scheme results November 2021 further mathematics advanced level in further mathematics paper-9fm0-4c A letter P from a shop sign is modelled as a uniform ... plane lamina which consists of a rectangular lamina, OABDE, joined to a semicircular lamina, BCD, along its diameter BD. OA = ED = a, AB = 2a, OE = 4a, and the diameter BD = 2a, as shown in Figure 1. Using the model, (a) find, in terms of π and a, the distance of the centre of mass of the letter P, from (i) OE (ii) OA (6) The letter P is freely suspended from O and hangs in equilibrium. The angle between OE and the downward vertical is α. Using the model, (b) find the exact value of tan α (2) _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ ______________________________________________________ [Show More]
