In the given Fig. 7(CF).2, if the dimensions of the two wires are the same and materials are different, Young's modulus is

A

A

B

B

C

Both

D

None of these

Text Solution

Verified by Experts

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