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 bottomof the lod and another road of 1 kg hangs from this lower wire. Find the longitudial strain in both wires. Area of cross section of each wire is `0.005 cm^2` and Young modulus of the metasl is `2.0xx10^11 Nm^-2. Take g=10ms^-2`
