The temperatures of the two ends A and B of a rod of length $25$ cm and uniform circular cross-section are $100°$C and $0°$C respectively. In the steady state, the temperature at a point $10$ cm from the end B is (ignore heat loss from the curved surface)
Answer: (D) $40°$C
In the steady state the temperature falls uniformly along the rod: $4°$C per cm. A point $10$ cm from B (which is at $0°$C) is at $40°$C.
