Two wires of diameter 0.25 cm, one made of steel and other made of brass are loaded as shown in figure. The unloaded length of the steel wire is 1.5 m and that of brass is 1.0 m. Young's modulus of steel is 2.0 x 1011 Pa and that of brass is 1.0 x 1011 Pa. The ratio of elongations of steel and brass wires. (∆lsteel∆lbrass = ?)
