A: Two wire A and B having equal cross sections made from the same material. The length of A is twice to the length of B, hence the increase in length of A is twice to the increase in length of B for a given same weight.
R: Increase in length of wire proportional to its length for a given same length.

A

Both are true and the reason is the correct explanation of the assertion.

B

Both are true but the reason is not correct explanation of the assertion.

C

Assertion is true, but the reason is false.

D

Both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Increase in length proportional to the original length hence assertion and reason are correct and the reason is the correct explanation of the assertion
