Question

If the radius of a wire stretched by a load is doubled, then its young's modulus will be * halved become one-fourth doubled remain unaffected

Answer 1

Young's Modulus is a property of material so it will remain unaffected. It does not depend on length are force stress or other factors.

It only depends on temperature

Answer 2

Answer:

Remain unaffected

Explanation:

The young modulus of any material is equal to the ratio of stress and the strain. Its formula is given by :

$Y=\dfrac{\sigma}{\epsilon}$

or

$Y=\dfrac{F/A}{\Delta L/L}$

The young modulus of any material is its inherited property. It only depends on the temperature and the pressure.

So, if the radius of a wire stretched by a load is doubled, then its young's modulus will remain unaffected. Hence, the correct option is (D).
