NEET Physics Elastic Behavior MCQ Question
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?
Elastic deformation
Plastic deformation
Thermal expansion
Magnetic attraction
Correct Answer
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.
