NEET Physics Young's Modulus Assertion Reason Question
Assertion (A): Steel is preferred in structural designs due to its higher Young's modulus compared to materials like copper, brass, and aluminum.
Reason (R): Young's modulus is a measure of a material's ability to withstand changes in length under tensile or compressive forces.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that steel requires a larger force to produce a small change in length, indicating a higher Young's modulus, making it more suitable for structural designs. This supports both the assertion and the reason, with the reason explaining the assertion.
