Neco Model Questions Vol1 2021 Physics Question 26
Practice objective / multiple choice question 26 from the 2021 Neco Model Questions Vol1 Physics examination.
A thin string of mass per unit length \(0.005\;\text{kg\,m}^{-1}\) is stretched between two fixed points \(0.80\;\text{m}\) apart. Its fundamental frequency is measured to be \(120\;\text{Hz}\). The string is then stretched uniformly to a length of \(1.00\;\text{m}\) while the tension remains unchanged, and the new fundamental frequency is found to be \(107\;\text{Hz}\) (to three significant figures). Determine the original tension in the string (in newtons).
