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 $$1$$cm. Then, the two wires will have.
the same stress and strain
the same stress but different strains
the same strain but different stresses
different stresses and strains
The correct option is A the same stress and strain
As same force is applied to each wire having equal area of cross-section, so stress is same but extensions will be different for wires of different materials. So, same stress but different strains are there.
