Question 69: Properties of Matter

Question

Young's modules of material of a wire of length '$$L$$' and cross-sectional area $$A$$ is $$Y$$. If the length of the wire is doubled and cross-sectional area is halved then Young's modules will be :

Accepted Answer

Young's modulus depends on the material not length and cross sectional area. So young's modulus remains same.

Answer

4 Y

Answer

2 Y

Answer

$$\mathrm{\frac{Y}{4}}$$

Answer

Y
