Young’s Modulus Independence – Rankers Physics

Fluid Statics: Practice Problem & Solution

The Young's modulus of wire of length L and radius r is Y. If the length and radius are reduced to \(\frac{L}{3}\) and \(\frac{r}{2}\), then its Young's modulus will be
\(\frac{Y}{4}\)
Y
6Y
\(\frac{2}{3}Y\)

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Fluid Statics. Understanding the underlying formula is key to arriving at the correct answer below:

Young's modulus is an intrinsic property of the material of the wire and is independent of its geometrical dimensions.
