To Find: The tension in the string.
Answer to Problem 77GP
Explanation of Solution
Given:
Mass of guitar string,
Length of string,
Tube opened at one end.
Formula used:
Write the expression for the speed of the sound.
Here,
T is the tension in the string.
Calculation:
Tension in the guitar string is determined by the following equation,
Now, determine the speed of the sound on the guitar ( v ),
The frequency of the string is
The fundamental standing frequency is equal to the frequency at the third harmonic tube.
Now, calculate the wavelength of third string is,
Where, n = third string = 3.
Now, calculate the speed of sound,
Substitute the values in the equation (tension) T
Conclusion:
The tension that should be in the string is
