Young's modules of materials of a wire of Length ' L ' and...

Young's modules of materials 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:

Options

A $\frac{Y}{4}$
B $4 Y$
CY
D2 Y

Correct answer

C. Y

Step-by-step solution

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