Question:medium
A weight \( W \) is connected to one end of a wire and the other end is fixed, length of wire is 1m. Area of cross-section is \( 10^{-5} \, \text{m}^2 \). Graph between change in length and weight is shown. Then calculate Young's modulus.

Show Hint
To calculate Young's modulus from a graph, find the slope of the graph (\( \Delta L \) vs. \( W \)), then apply the formula \( Y = \frac{F/A}{\Delta L/L} \).
