The ends of a uniform metal rod of length 100 cm and area of cross-section 2 cm2 are maintained at 0 °C and 100 °C. At the mid point of the rod. heat is supplied at a constant rate of 40 Js−1. If the temperature gradient on the higher temperature side of the rod in steady state is 50x °Cm−1. then the value of x is
(Thermal conductivity of the metal = 400 Js−1m−1K−1)
