Question

Assertion : Steel is more elastic than rubber.

Reason : For same strain , steel requires more stress to be produced in it .

(a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion 

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

(c) If Assertion is true, but the Reason is false.

(d) If Assertion is false but the Reason is true.

Answer 1

Correct option (a) If both Assertion and Reason are true and the Reason is correct explanation of the Assertion 

Explanation :

Elasticity depends upon Young's modulus which is more for steel as more stress is required to produce same strain i.e., reason is true explanation of assertion.
