One end of a metal wire is fixed to a ceiling and a load of 2 kg hangs from the other end. A similar wire is attached to the bottom of the load and another load of 1 kg hangs from this lower wire. Find the longitudinal strain in both wires. Area of cross section of each wire is `0.005 cm^2` and Young modulus of the metal is `2.0xx10^11 Nm^-2.` Take `g=10ms^-2`
