Correct Answer: Option n
Explanation:
(a) Elastic limit is the point on a load/extension graph beyond which Hooke's law is no longer obeyed.
(b) Hooke's law of elasticity states that the extension (e) in an elastic material (wire) is directly proportional to the force (load) applied, provided the elastic limit is not exceeded.
