Three wires P, Q and R of the same material and length have radii 0.1 cm, 0.2 cm and 0.3 cm respectively. Which wire has the highest value of Young's modulus of elasticity?

All have the same value

Text Solution

Verified by Experts

The correct Answer is:

Young's modulus depends upon the nature of material and not the radii of the wires.
