Question

Assume that the young's modulus of a wire of length l and radius r is y what will happen to young's modulus if the radius is doubled and length is halfed

Answer 1

Young's modulus becomes half of the initial

Answer 2

Answer:

The young's modulus of a material will always remain constant.

Explanation:

Young's modulus of a material is a constant quantity, and it does not depend on the dimension of a material.

Young's modulus is given by,

Y = FL/AΔL

If the length and area(radius) of a material are altered, it will be automatically reflected in the force required(F) and change in length(ΔL), and these parameters will vary but the young's modulus will always remain constant.
