Questions
Two perfectly identical wires are in unison. When the tension in one wire is increased by 1%, then on sounding them together 3 beats are heard in 2 sec. The initial frequency of each wire is :
detailed solution
Correct option is D
Similar to Q. 30 Initial frequency of each wire (n) =(Number of beats heared per sec)×200(per centage change in tension of the wire) =(3/2)×2001=300sec−1Talk to our academic expert!

A metal wire of diameter 1.5 mm is held on two knife edges separated by a distance 50 cm the tension in the wire is 100 N the wire vibrating with its fundamental frequency and vibrating tuning fork together produces 5 beats per second. The tension in the wire is then reduced to 81 N, when the two are excited, beats are heard at the same rate. Calculate frequency of the fork.
