Question

If you go on increasing the stretching force on a wire in a guitar its frequency.

• A. Increases
• B. Decreases
• C. Remains unchangedd
• D. None of the above

Answer 1

Answer: (A)

Increases

We know that the frequency of stretching string is given by, $f=\frac{1}{2l}\sqrt{\frac{T}{\mu }}$

where $l=$ length of string, $T=$ stretching force or tension and $\mu =$ mass per unit length.

Thus, $f\propto \sqrt{T}$

So, if the stretching force $T$ is increased, the frequency is also increasing.
