NEET Physics Elastic Behavior MCQ Question
Which of the following statements about the elastic behavior of materials is correct?
Elastomers can undergo significant deformation and return to their original shape without obeying Hooke's law.
All materials behave elastically within their elastic limit, following Hooke's law strictly.
The bulk modulus is defined as the ratio of volumetric strain to hydraulic stress.
Only rigid bodies can be deformed when subjected to external forces.
Correct Answer
Detailed Explanation
Elastomers, such as rubber, can be stretched significantly and still return to their original shape, indicating they do not strictly obey Hooke's law. This is highlighted in the NCERT context discussing the stress-strain behavior of materials like rubber and the elastic tissue of the aorta.
