In an experiment, brass and steel wires of length 1 m each with areas of cross-section 1mm2 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 requires to produce a net elongation of 0.2 mm is [Take, the Young’s modulus for steel and brass are • respectively 120 𝑿 10^9 N/m2 and 60 𝑿 10^9 N/m2] • (2019 Main) • IIT JEE Mains and Advanced PYQ: Properties of Matter #neet #jeemain #jeeadvance #physics#pyq
