If the length of a wire is made double and radius is halved of its respective values. Then, the Young's modulus of the material of the wire will :

remain same

become 8 times its initial value

become

\dfrac14

th of its initial value

become 4 times its initial value

Answer and worked solution

Official answer: A

Material constant. Young's modulus depends only on the material, not on the wire's dimensions.
