Neco Model Questions Vol1 2025 Physics Question 41
Practice objective / multiple choice question 41 from the 2025 Neco Model Questions Vol1 Physics examination.
A string of linear mass density \(5.0\times10^{-3}\) kg m\(^{-1}\) is fixed at both ends. Initially its length is \(0.80\) m and the tension in the string is \(40\) N. The string vibrates in its fundamental mode. The string is then shortened to \(0.50\) m and the tension is increased to \(90\) N. What is the new fundamental frequency of the string? Give your answer in hertz (Hz), correct to the nearest whole number.
