Assertion A metallic rod is fixed from two ends as shown in figure. When the temperature is increased compressive stresses are developed in the rod.

Reason At higher temperature, natural length of the rod will be more.

A

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are correct but Reason is not the correct explation os Assertion.

C

If Assertionis true bur Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
At higher temperature natural length is more. It means rod is compressed.
