NEET Physics Young's Modulus MCQ Question
Type: MCQ-fact-Easy-Class 11
What is the yield strength of mild steel as stated in the context?
A
300 × 10^6 N/m²
B
200 × 10^6 N/m²
C
400 × 10^6 N/m²
D
100 × 10^6 N/m²
Correct Answer
Option A
Detailed Explanation
The NCERT context specifies that mild steel has a yield strength (σy) of about 300 × 10^6 N/m², which is essential for ensuring that the load does not deform the rope permanently.
