Mechanical Properties of SolidsGiven below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R)
Assertion (A) : The property of body, by virtue of which it tends to regain its original shape when the external force is removed, is Elasticity.
Reason (R) : The restoring force depends upon the bonded inter atomic and inter molecular force of solid.
In the light of the above statements, choose the correct answer from the options given below :
Mechanical Properties of SolidsGiven below are two statements: one is labelled as Assertion A and the other is labelled as Reason R
Assertion (A) : Steel is used in the construction of buildings and bridges.
Reason (R) : Steel is more elastic and its elastic limit is high.
In the light of above statements, choose the most appropriate answer from the options given below
