Steel wire of length ' LL ' at 40∘C40^{\circ} \mathrm{C} is suspended from the ceiling and then a mass ' m′m^{\prime} is hung from its free end. The wire is cooled down from 40∘C40^{\circ} C to 30∘C30^{\circ} C to regain its original length ′L′.^{\prime} L^{\prime} . The coefficient of linear thermal expansion of the steel is 10−5/∘C,10^{-5} /^{\circ} C, Young's modulus of steel is 1011N/m210^{11} N / m^{2} and radius of the wire is 1mm1 \mathrm{mm}. Assume that L>>L>> diameter of the wire. Then the value of ' mm ' in kg is nearly
