    On heating one end of a rod, the temperature of whole rod will be uniform when

    A)            K = 1                                        

    B)            K = 0

    C)            K = 100                                    

    D)            \[K=\infty \]

    Correct Answer: D

    Solution :

                       \[\frac{dQ}{dt}=-KA\frac{d\theta }{dx}\]; when \[K=\infty ,\ \ \frac{d\theta }{dx}=0\] i.e. q  is independent of x i.e. constant or uniform.
