The end A of rod AB of length 1 m is maintained at `80^(@)`C and the end B at `0^(@)`C. The temperature at a distance of 60 cm from the end A is

A

`16^(@)`C

B

`32^(@)`C

C

`48^(@)`C

D

`64^(@)`C

Text Solution

Verified by Experts

b) `(DeltaT)/l = (80-0)/1 = 80 cm^(-1)`
`DeltaT_(1) = (0.60)(80) = 0.48^(@)`C
Decrease in temprature after a distance of 60 cm is `48^(@)`C and hence actual temperatures is `(80-48)^(@)`C = `32^(@)`C.
