Two rods of same length and same material having area of cross section A and 4A respectively are joined as shown in the figure. If `T_(A)` and `T_(B)` are temperatures of free ends in steady state. The temperature of junction point C is (Assume no heat loss wil take place through lateral surface)

`(T_(A)-T_(B))/2`

`(T_(A)+T_(B))/2`

`(T_(A)+4T_(B))/5`

`(4T_(A)+T_(B))/5`
