A wave moves with speed `300 m//s` on a wire which is under a tension of `500 N`. Find how much tension must be changed to increase the speed to `312 m//s`?

Explanation

To solve the problem step by step, we will use the relationship between wave speed, tension, and linear mass density of the wire.

### Step 1: Understand the relationship between wave speed and tension
The speed of a wave on a string or wire is given by the formula:
\[ V = \sqrt{\frac{T}{\mu}} \]
where:
