The fundamental frequency of a sonometer wire increases by 5Hz, if its tension is increased by `21%` .How will the frequency be affected if the length is increased by `10%` /

Explanation

To solve the problem step by step, we will use the formula for the fundamental frequency of a sonometer wire and analyze the changes in tension and length.

### Step 1: Understand the relationship between frequency, tension, and length
The fundamental frequency \( f \) of a sonometer wire is given by the formula:
\[ f = \frac{1}{2L} \sqrt{\frac{T}{\mu}} \]
where:
