Answer» the same STRESS different stress the same strain different strain Solution :In stress `= F/A,` F is defoeming force and A is constant. `therefore` Hence, stress is same so option (A) is correct. `implies ` Strain `= F/Y` Both wire having same DEFORMING force but different Young.s MODULUS and hence two wires will have different strain so, option (D) is correct.
