Two violinists are trying to tune their instruments in an orchestra. One is producing the desired frequency of 440.0 hz. The other is producing a frequency of 448.4 hz. By what percentage should the out-of-tune musician change the tension in his string to bring his instrument into tune at 440.0 hz?

Percentage change in tension is 3.8%

Explanation:

We have given initially frequency = 440 Hz

Let tension in the string at this frequency is

Now second frequency is

Frequency in string is given by

From the relation we can say that

Percentage change in tension is equal to

%

So percentage change in tension is 3.8%
