The Young's modulus of a wire of length L and radius r is Y. If the length is reduced to L/2 and radius to r/2, its Young's modulus will be
Correct answer: C. Y
- A. Y/2
- B. 2Y
- C. Y
- D. 4Y
Explanation
Young's modulus (Y) is a material property and does not depend on the dimensions of the specimen. Therefore, reducing the length and radius of the wire does not change its Young's modulus.
