Igcse Model Questions Vol1 2024 Physics Question 21
Practice objective / multiple choice question 21 from the 2024 Igcse Model Questions Vol1 Physics examination.
A string has a linear mass density of \(0.020\ \text{kg m}^{-1}\). When the tension in the string is \(80\ \text{N}\) it supports a standing wave of frequency \(5.0\ \text{Hz}\). If the tension is increased so that the wavelength of the same standing wave becomes \(20.0\ \text{m}\) (the frequency remains unchanged), what is the new tension in the string? Give your answer in newtons.
