The speed of a transverse wave, going on a wire having a length 50 cm and mass 5.0 g, is 80 m/s. The area of cross-section of the wire is 1.0 \[m{{m}^{2}}\] and its Young?s modulus is\[16\times {{10}^{11}}N/{{m}^{2}}\]. Find the extension of the wire over its natural length. If it is\[a\times {{10}^{-2}}mm\]. Find value of a.
