Igcse Model Questions Vol1 2021 Physics Question 15
Practice objective / multiple choice question 15 from the 2021 Igcse Model Questions Vol1 Physics examination.
A string of length 0.80 m is fixed at both ends. When a tension of 40 N is applied, its fundamental frequency is 120 Hz. The string is then cut into two equal pieces, each of length 0.40 m, and the same tension of 40 N is applied to each piece. The fundamental frequency of each piece is measured to be 210 Hz. Using these two measurements, calculate the percentage difference between the linear mass densities obtained from the two experiments. Give your answer as a percentage to the nearest whole number.
