Question
The Young's modulus of steel wire of radius $r$ and length L is Y . If the radius r and length L of the wire are doubled then the value of Y
Options
A.increases by two times
B.reduces by half
C.remains unchanged
D.becomes one fourth
Solution
Sol. [Key Concept: Young's modulus is a material property, independent of the wire's radius or length, so it remains unchanged.]
Young's modulus is the property of material not depends on dimensions of material.
