17.6 Exercise 9

Avg difficulty 2.5

Two identical strings, of identical lengths of 2.00 m and linear mass density of μ=0.0065kg/m,\mu = 0.0065 \text{kg}/\text{m}, are fixed on both ends. String A is under a tension of 120.00 N. String B is under a tension of 130.00 N. They are each plucked and produce sound at the n=10n = 10 mode. What is the beat frequency?
