A copper wire and a steel wire of the same diameter and length are connected end to end and a force is applied, which stretches their combined length by 1 cm. The two wires will have
Text Solution
Verified by ExpertsThe correct answer is:
D
.
In the present case, force applied and area of cross-section of wires are same, therefore stress has to be the
same.
Since the Young’s modulus of steel wire is greater than the copper wire, therefore, strain in case of steel
wire is less than that in case of copper wire.
