Neco Model Questions Vol1 2019 Physics Question 38
Practice objective / multiple choice question 38 from the 2019 Neco Model Questions Vol1 Physics examination.
A string 1.2 m long is fixed at both ends. Its linear mass density varies linearly from \(0.5\ \text{g m}^{-1}\) at one end to \(1.5\ \text{g m}^{-1}\) at the other end. The string is under a uniform tension of 80 N and vibrates in its fundamental mode with an observed frequency of 120 Hz. Calculate the average linear mass density of the string and the theoretical fundamental frequency. State whether the observed frequency is consistent with the theoretical value within a 5 % tolerance.
