Question 89: Properties of Matter

Question

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 :

Accepted Answer

Young's modulus of matter depends on material of wire and is independent of the dimensions of the wire. As the material remains same so Young's modulus also remain same.

Answer

remain same

Answer

become 8 times its initial value

Answer

become $$\frac{1}{4}$$ of its initial value

Answer

become 4 times its initial value
