The Young's modulus of steel wire of radius r and length L is Y ....
The Young's modulus of steel wire of radius and length is . If the radius and length of the wire are doubled then the value of
Options
- Aincreases by two times
- Breduces by half
- Cremains unchanged
- Dbecomes one fourth
Correct answer
C. remains unchanged
Step-by-step solution
Young's modulus is an intrinsic property of the material of the wire.
It depends only on the nature of the material and its temperature, and is independent of the dimensions of the wire such as length and radius .
Therefore, when the radius and length of the steel wire are doubled, its Young's modulus remains unchanged.
Answer: remains unchanged
