Very easy level · Asked in State AE, State JE, GPSC AE

If the radius of a wire stretched by a load is doubled, then its Young’s Modulus will

Solution

Concept

Young modulus is a material property

Step-by-step solution

1. E depends only on the material. 2. Changing the radius does not change E.

Explanation

The modulus is independent of dimensions.

Why the other options are wrong

Doubling, halving or quartering is wrong.

Shortcut

E is a material constant.

Correct answer: D) None of the above
