A copper wire and a steel wire of the same diameter and length are joined end to end and a force is applied which stretches their combined length by 1cm. Then, the two wires will have.

Thank you for asking this question. The options for this question are missing, here are the missing options:
a) The same stress and strain
b) The same stress but different strains
c) The same strain but different stresses
d) Different stresses and strains
The correct answer for this question is Option B) The same stress but different strains
If there is any confusion please leave a comment below.
Here the stress will remain same and the value of strain will be different ....
stress is equals to force upon area and it is given that the same force is applied and the area of cross section is same for both the wire ...
strain depends upon the Young's modulus of the wire and elongations...
which will undoubtedly be different for these two wires cells they are of two different materials ..
