Question 44 of 118

If the length of a wire is made double and radius is halved of its respective values. Then, the Young's modulus of the material of the wire will :

Show answer and solution

Answer: (A) Remain same

Young's modulus is the ratio of stress to strain.
Young's modulus is a property of a material, and it does not depend on the geometry i.e. length and the radius of the wire. Therefore, the Young's modulus of the wire will remain same.
