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.

Answer» Both are true and the reason is the correct explanation of the ASSERTION. Both are true but the reason is not correct explanation of the assertion. Assertion is true, but the reason is false. Both assertion and reason are false. Solution :INCREASE in LENGTH PROPORTIONAL to the ORIGINAL length hence assertion and reason are correct and the reason is the correct explanation of the assertion
