Questions
The temperature at the two ends A and B of a rod of length 25 cm and circular cross-section are 1000C and 00C, respectively. In the steady state, the temperature at a point 10 cm from the end B is (Ignore loss of heat from curved surface of the rod)
detailed solution
Correct option is D
From the equation, θx=ΔtlGiven, t1=100∘C,t2=0∘C,l=25cm and x=10cmθ10=100−025⇒θ10=4⇒θ=40∘CTalk to our academic expert!
