In a steady state of thermal conduction, temperature of the ends A and B of 20cm long rod are 100^(0) C and 0^(@) C respectively. The temperature of the rod at a point at a distance of 6 cm from the end A of the rod is

The two ends of a metal rod are maintained at temperatures 100^(@)Cand110^(@)C . The rate of flow in the rod is found to be 4.0 J/s. If the ends are maintained at temperatures 200^(@)Cand210^(@)C , the rate of heat flow will be :
