Question

Assertion (A) : Ductile metals are used to prepare thin wires.
Reason (R) : In the stress-strain curve of ductile metals, the length between the points representing elastic limit and breaking point is very small.

• A. Both (A) and ( R) are true and ( R) is the correct explanation of (A)
• B. Both (A) and (R) are true and (R) is not correct explanation of (A)
• C. (A) is true but (R ) is false.
• D. (A) is false but (R ) is true.

Answer 1

Answer: (C)

(A) is true but (R ) is false.

Ductility is the property of metals to get drawn into thin wires and such metals have considerable distanc between the points representing elastic limit and breaking point .
