A cubical frame is made by connecting 12 identical uniform conducting rods as shown in the figure. In the steady state the temeprature of junction A is `100^(0)C` while that of the G is `0^(0)C`. Then

A

B will be Hotter than H

B

Temperature of F is `40^(0)C`

C

Temperature of D is `66.67^(0)C`

D

Temperature of E is `50^(0)C`

Text Solution

Verified by Experts

The correct Answer is:
B

`100^(@)C-lr-(l)/(2)r-lr=0^(@)C`
`implieslr=40^(@)C,thereforet_(F)=0^(@)+lr=40^(@)C`
