A rod of length L and uniform cross-sectional area has varying thermal conductivity which changes linearly from 2K at end B to K at the other end A. The ends A and B of the rod are maintained at constant temperature 100∘C and 0∘C, respectively. At steady state, the graph of temperature : T=T(x) where x= distance from end A will be

1.	A rod of length L and uniform cross-sectional area has varying thermal conductivity which changes linearly from 2K at end B to K at the other end A. The ends A and B of the rod are maintained at constant temperature 100∘C and 0∘C, respectively. At steady state, the graph of temperature : T=T(x) where x= distance from end A will be
Answer» A rod of length $L$ and uniform cross-sectional area has varying thermal conductivity which changes linearly from $2 K$ at end $B$ to $K$ at the other end $A$ . The ends $A$ and $B$ of the rod are maintained at constant temperature $100^{\circ} C$ and $0^{\circ} C$ , respectively. At steady state, the graph of temperature : $T = T (x)$ where $x =$ distance from end $A$ will be
