Question

Two identical piano wires, kept under the same tension T have a fundamental frequency of 600 Hz. The fractional increase in the tension ofone ofthe wires which will lead to occurrence of 6 beats/s when both the wires oscillate together would be

Accepted Answer

Correct answer: B. (b) As tI= 12L T . ∴ u= 1 T2T TT=2 =2 6600=0.02
