The figure shows the stress-strain graph of a certain substance. Over which region of the graph is Hooke's Law obeyed?
1 \(CD\)
2 \(BC\)
3 \(OD\)
4 \(AB\)
Explanation:
For Hooke's law, stress \(\propto\) strain i.e., the graph between stress and strain is a straight line.

Statement A : For rubber, strain is more as compared to steel. Statement B : Rubber is less elastic than steel
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
The elasticity of a material is the ratio of stress and strain. In given case, the strain produced in the rubber is more than that in steel. As, rubber is less elastic than steel. Therefore, option (3) is correct.

Which of the following statement (s) is/are correct regarding to elastomers? I. It can be elastically stretched to a large value of strain. II. These materials do not obey Hooke's law III. Young's modulus of elastomers is very large.
1 Both I and II
2 Both II and III
3 Both I and III
4 I, II and III
Explanation:
Elastomers are those materials which can be elastically stretched to a large value of strain. Elastic region for them is very large but they do not obey Hooke's law. Thus, Young's modulus of elastomers is very small. So, statements I and II are correct but III is incorrect.
