Two tuning forks produce `5 beats` when sounded together.` A` is in unison with ` 40 cm` length of a sonometer wire under a constant tension and `B` is in unison with the same wire of length `40.5 cm` under the same tension. Calculate fundamental frequency of the forks.

Explanation

To solve the problem step by step, we will follow the information provided in the video transcript and apply the relevant physics concepts.

### Step 1: Understanding Beats
When two tuning forks produce beats, the number of beats per second is equal to the absolute difference in their frequencies. Given that there are 5 beats, we can write:
\[ |f_A - f_B| = 5 \quad \text{(Equation 1)} \]

### Step 2: Frequency of Fork A
The frequency of a tuning fork can be determined using the formula for the fundamental frequency of a vibrating string:
