JEE Main Physics question

Statement 1: Ductile metals are used to prepare thin wires.

Statement 2: In the stress-strain curve of ductile metals, the length between the points representing elastic limit and breaking point is very small.

(A)Assertion is True, Reason is True; Reason is correct explanation for Assertion
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is FalseCorrect
(D)Assertion is False, Reason is True

Answer: (C)

Solution

Statement 1 is true: ductility is precisely the ability of a metal to be drawn into thin wires. Statement 2 is false: for a ductile metal, the region of the stress-strain curve between the elastic limit and
