NEET Physics Elastic Behavior MCQ Question
Type: MCQ-numerical-Hard-Class 11
A metallic wire is stretched to produce a tensile stress of 2.0 × 10^7 N/m². If the tensile strain produced is 0.001, what is the Young's modulus of the material of the wire?
A
0 × 10^10 N/m²
B
0 × 10^9 N/m²
C
0 × 10^8 N/m²
D
0 × 10^7 N/m²
Correct Answer
Option A
Detailed Explanation
Young's modulus is calculated using the formula E = stress/strain. Substituting the given values, E = (2.0 × 10^7 N/m²) / 0.001 = 2.0 × 10^10 N/m².
