1.	A long rod is heated from one end and the bar attains the conditions of steady state. (Given, emissivity of the material of rod = 0.9, coefficient of thermal conductivity of rod =100"Wm"^(-1)""^(0)C^(-1), radius of rod = 10cm = 0.1 m) This setup is placed in vacuum. If theta is temperature at steady state of any section of rod and (d^(2)theta)/(dx^(2))=2.N^(2).thetaxx10^(-2). Where, x is the distance of section from end, find the value of N.
