Three rods of the same length and the same area of the cross-section are joined. The temperature of two ends one `T_(1)` and `T_(2)` as shown in the figure.
As we move along the rod the variation of temperature are as shown in the following [Rods are insulated from the surrounding except at the faces]

Options

A. `(K_(1))/(sqrt(3))=(K_(2))/(3)=(K_(3))/(1)`
B. `(K_(1))/(3)=(K_(2))/(1)=(K_(3))/(sqrt(3))`
C. `(K_(1))/(3)=(K_(2))/(sqrt(3))=(K_(3))/(1)`
D. `(K_(1))/(sqrt(3))=(K_(2))/(1)=(K_(3))/(3)`

Answer

C
