Answer 1

CONCEPT:

Hooke’s law and Modulus of Elasticity: According to this law, within the elastic limit, stress is proportional to the strain.

i.e. stress ∝ strain

or,

\(\frac{{stress}}{{strain}} = constant = E\)

Where E = modulus of elasticity.

EXPLANATION:

From the above relation, it is very much clear that Hook’s law gives information about the relationship between stress and strain. It does not define stress or strain. Thus, option 1 and 2 is incorrect.
From the above relation, it is very much clear that Hook's law defines the modulus of elasticity. Hence option 3 is correct.

Hooke’s law does nor defines about Elastic limit. Thus, option 4 is incorrect.
