Physics-Elastic Behavior
NEET Physics Elastic Behavior MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a helical spring being stretched by applying a force at its ends. Which of the following phenomena best describes the reason for the increase in the length of the spring?
A
Elastic deformation
B
Plastic deformation
C
Thermal expansion
D
Magnetic attraction
Correct Answer
Option A
Detailed Explanation
When a helical spring is stretched, it undergoes elastic deformation, which means it changes shape under the application of force but returns to its original form once the force is removed, as described in the elastic behavior of solids.
