Three rods of identical cross - section and length are made of three different material of thermal conductivity k_(1) , k_(2) and k_(3) respectively. They are joined together at their ends to make a long rod (See figure). One end of the long rod is maintained at 100^(@)C and the other at 0^(@)C ( See figure ). If the joints of the rod are at 70^(@)C and 20^(@)C in steady state and there is no loss of energy form the surface of the rod, the correct relationship between k_(1), k_(2) and k_(3) is
