JEE MAIN - Physics (2022 - 29th July Morning Shift - No. 8)
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 :
remain same
become 8 times its initial value
become $$\frac{1}{4}$$ of its initial value
become 4 times its initial value
Explanation
Young's modulus of matter depends on material of wire and is independent of the dimensions of the wire. As the material remains same so Young's modulus also remain same.
