The C string of a certain musical instrument is overstretched. The accurate frequency of this note should be 261.6 Hz, which is emitted by a tuning fork. Six beats per second are heard when the string is sounded together with a tuning fork. What is the frequency produced by the string of this instrument?
A) 267.6 Hz B) 255.6 Hz C) 133.8 Hz D) 127.8 Hz E) Not enough information to tell if the frequency is above or below the correct frequency.
The answer is in the images. Page number is mentioned at right top. In the question how the overstretching is done is not mentioned properly. So I give all three possibility with proper explanation. Choose anyone as per requirements.
