Q4. a) The fundamental frequency, f (Hz), of a string of length 2 (m), attached at either end, so that the tension is T (N), is given by: T 1 2L , р where p is mass per unit length of the string (kg/m), 1) Find the following partial derivatives: af af and al' at др af (6 marks) ii) Calculate f based on the following values: L = 1.05m, T = 44.1N and p = 0.25 x 10-3kg/m (1 mark) 110) Derive an equation to estimate the maximum error forf in Hz, and use it to find this error under the assumption that the values given above for L. Tland p are only accurate to +1%. (8 marks)
