The temperature of two diagonally opposite points and T and \[\sqrt{2}\]T respective in the steady state. Assuming that only heat conduction takes place, what will be the temperature difference between other two points                                       [BCECE 2005]

A)            \[\frac{\sqrt{2}+1}{2}T\] 

B)            \[\frac{2}{\sqrt{2}+1}T\]

C)            0    

D)            None of these

Correct Answer: C

Solution :
