Neco 2025 Physics Question 26
Practice objective / multiple choice question 26 from the 2025 Neco Physics examination.
A string of length \(0.80\ \text{m}\) fixed at both ends vibrates with a fundamental frequency of \(100\ \text{Hz}\). When the tension in the string is increased, the frequency of the third harmonic becomes \(540\ \text{Hz}\). Assuming the linear mass density of the string does not change, by what factor is the tension increased? Give your answer as a decimal to two significant figures.
