There are two wires, each produces frequency of 500Hz. By what percentage tension in one wire is increased so that 5 beats per second can be heard?

Explanation

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

### Step 1: Understand the relationship between frequency and tension
The frequency \( f \) of a wire is related to the tension \( T \) in the wire by the formula:
\[ f \propto \sqrt{T} \]
This means that if we change the tension, the frequency will change according to the square root of the tension.
