Igcse Model Questions Vol1 2022 Physics Question 15
Practice objective / multiple choice question 15 from the 2022 Igcse Model Questions Vol1 Physics examination.
A string of length \(0.80\ \text{m}\) is fixed at both ends. When the tension in the string is \(40\ \text{N}\) its fundamental frequency is \(120\ \text{Hz}\). If the tension is increased to \(90\ \text{N}\) and the linear mass density of the string remains unchanged, what is the new fundamental frequency? Give your answer in hertz, rounded to the nearest whole number.
