Question

With increase in tension in a string the frequency of vibration :

• A. increases
• B. decreases
• C. remain unaffected
• D. none of these

Answer 1

The correct option is A increases

With the increase in the tension in a string, the frequency of the vibration also increases.

As,

$f=\frac{n}{2L}\sqrt{\frac{T}{\mu }}\left[f\alpha \sqrt{T}\right]\downarrow$

Directly proportional

Hence option (A) is correct.
