A steel wire of length 4 m and diameter 5 mm is stretched by 5kg-wt. Find the increase in its length if the Young's modulus of steel wire is `2.4 xx 10^(12) dyn e cm^(-2)`

Explanation

To find the increase in length of a steel wire when a force is applied, we can use the formula derived from Young's modulus. Here are the steps to solve the problem:

### Step 1: Understand the formula for Young's Modulus
Young's modulus (Y) is defined as the ratio of stress to strain:
\[ Y = \frac{\text{Stress}}{\text{Strain}} \]
Where:
- Stress = \(\frac{F}{A}\) (Force per unit area)
- Strain = \(\frac{\Delta L}{L_0}\) (Change in length per original length)
