Properties Of Matter

A metal block of mass \(\mathrm{m}\) is suspended from a rigid support through a metal wire of diameter \(14 \mathrm{~mm}\). The tensile stress developed in the wire under equilibrium state is \(7 \times 10^{5} \mathrm{Nm}^{-2}\). The value of mass \(\mathrm{m}\) is _________ \(\mathrm{kg}\). (Take, \(\mathrm{g}=9.8 \mathrm{~ms}^{-2}\) and \(\pi=\frac{22}{7}\) )
