Gce Model Questions Vol1 2020 Physics Question 47
Practice objective / multiple choice question 47 from the 2020 Gce Model Questions Vol1 Physics examination.
A string of length \(1.20\ \text{m}\) and linear mass density \(5.0\times10^{-3}\ \text{kg m}^{-1}\) is fixed at both ends. When a tension of \(30\ \text{N}\) is applied, its fundamental frequency is \(f_{1}\). The tension is then increased by hanging an additional \(5.0\ \text{kg}\) mass over a frictionless pulley attached to the string, so that the new tension is \(T_{2}=T_{1}+mg\). (i) Find the new fundamental frequency \(f_{2}\). (ii) Determine the ratio \(f_{2}/f_{1}\).
