Gce Model Questions Vol1 2023 Physics Question 6
Practice objective / multiple choice question 6 from the 2023 Gce Model Questions Vol1 Physics examination.
A stretched string of length \(1.20\ \text{m}\) is fixed at both ends and has a linear mass density of \(0.025\ \text{kg\,m}^{-1}\). When the string is plucked, the second harmonic has a frequency of \(120\ \text{Hz}\). The tension in the string is then increased by \(20\%\). What is the new frequency of the fundamental (first harmonic) after the tension increase? Give your answer to the nearest hertz.
