The breaking stress of the material of a wire is \[6\times {{10}^{6}}N{{m}^{-2}}\]. Then density \[\rho \] of the material is \[3\times {{10}^{3}}kg\,{{m}^{-3}}\]. If the wire is to break under its own weight, the length (in metre) of the wire made of that material should be \[\left( take\,g=10\text{ }m{{s}^{-2}} \right)\]
