STANDARD Physics Elastic Moduli MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Identical spring of steel and copper (Yₛₜₑₑₗ > Ycopper) are equally stretched.
A
Less work is done on copper spring.
B
Less work is done on steel spring.
C
Equal work is done on both the springs.
Correct Answer
Option B
Detailed Explanation
Since Young's modulus for steel is greater than that for copper, less work is needed to achieve the same extension in the steel spring.
