Igcse Model Questions Vol1 2017 Physics Question 35
Practice objective / multiple choice question 35 from the 2017 Igcse Model Questions Vol1 Physics examination.
A string of length \(L=1.20\) m, mass per unit length \(\mu=0.010\) kg m⁻¹, is fixed at both ends.\n(a) If its fundamental frequency is \(120\) Hz, find the tension in the string.\n(b) The tension is then increased by \(25\) %. What is the frequency of the third harmonic under the new tension?\n(c) If a small mass is attached at the midpoint, creating a node there, determine the frequency of the fundamental mode of the whole system under the original tension.
