Two wires `A` and `B` have Young moduli in the ratio `1:2` and ratio of lenghts is `1:1`. Under the application of same stress the ratio of elonagations is

`1:1`

`1:2`

`2:1`

`1:4`

Text Solution

Verified by Experts

The correct Answer is:

`e = (Fl)/(AY), (e_(1))/(e_(2)) = (l_(1))/(l_(2)) (Y_(2))/(Y_(1))`
