Gce Model Questions Vol1 2025 Physics Question 48
Practice objective / multiple choice question 48 from the 2025 Gce Model Questions Vol1 Physics examination.
A string of length \(L = 1.20\ \text{m}\) is fixed at both ends. Its linear mass density is \(\mu = 8.0\times10^{-3}\ \text{kg m}^{-1}\). The tension varies linearly from \(T_{1}=40\ \text{N}\) at one end to \(T_{2}=100\ \text{N}\) at the other end. Assuming the wave speed at any point is \(v(x)=\sqrt{T(x)/\mu}\) with \(T(x)=T_{1}+\frac{(T_{2}-T_{1})}{L}x\), determine the fundamental frequency of the string.
