Assertion If length of a wire is halved,...

Assertion If length of a wire is halved, its Young's modulus of elasticity will become two times.
Reason The ratio of longitudinal stress and longitudinal strain is called Young's modulus of elasticity.

A

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

B

If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Young's modulus is the property of material . It does not depend on length of the wire.
