In an experiment, brass and steel wires of length 1 m each with areas of cross section 1mm^(2) are used. The wires are connected in series and one end of the combined wire is connected to a rigid support and other end is subjected to elongation. The stress required to produce a net elongation of 0.2 mm is, [Given, the Young’s Modulus for steel and brass are, respectively, 120 xx 10^(9) N//m^(2) and 60 xx 10^(9) N//m^(2)

A light rod of length 2 m is suspended from the ceiling horizontally by means of two vertical wires of equal length tied to its ends. One of the wires is made of steel and is of cross section 0.1 cm^(2) . The other wire is a brass of cross section 0.2 cm^(2) . A weight is suspended from a certain point of the rod such that equal stress are produced in both the wires. Which of the following are correct?
