In the given figure, if the diamensions of the wires are the same and materials are different, Young's modulus is more for

A

A

B

B

C

Both

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
a
`F = ((YA)/(I)) Delta I`
i.e., `F - Delta I` graph is a straight line with slope `(YA)/(I)` or slope proportional to Y.
`("slope")_(A) gt ("slope")_(B) :. Y_(A) gt Y_(B)`
