Young's modulus of a wire is 2 xx 10^(11...

Young's modulus of a wire is `2 xx 10^(11) N//m^(2)`. The wire is stretched by a 5 kg weight. If the radius of the wire is doubled, its Young's modulus

A

will become half

B

will be doubled

C

will not change

D

will increase by four times

Text Solution

Verified by Experts

The correct Answer is:
C

Y will not change by changing L, M and r. It is a constant of the material.
