Physics-Young's Modulus
NEET Physics Young's Modulus MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a stress-strain graph for a material. Which segment of the graph is used to determine the Young's modulus of the material?
A
The initial linear portion of the graph.
B
The point where the graph becomes non-linear.
C
The entire graph from start to finish.
D
The region beyond the elastic limit.
Correct Answer
Option A
Detailed Explanation
Young's modulus is determined from the initial linear portion of the stress-strain graph, where stress is proportional to strain.
