Neco 2017 Physics Question 9
Practice objective / multiple choice question 9 from the 2017 Neco Physics examination.
A string of length \(1.2\,\text{m}\) is fixed at both ends. When the tension in the string is \(80\,\text{N}\) it vibrates in its fundamental mode with a frequency of \(100\,\text{Hz}\). The linear mass density of the string is uniform. If the tension is increased to \(180\,\text{N}\), what is the new fundamental frequency (in Hz, to the nearest whole number)?
