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: (a) remain same (b) become 8 times its initial value (c) become 1/4 of its initial value (d) become 4 times its initial value

Answer: (a). Young's modulus is a property of the material; changing length or radius does not change it. So the answer is (a) remain same.

Young's Modulus & Elongation

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)

Young's modulus is a property of the material; changing length or radius does not change it.
So the answer is (a) remain same.
