The two ends of a metal rod are maintained at temperature `100^(@)C` and `110^(@)C`. The rate of heat flow in the rod is found to be `4.0 J//s`. If the ends are maintained at temperature s `200^(@)C` and `210^(@)C`. The rate of heat flow will be

`16.8 J//s`

`8.0 J//s`

`4.0 J//s`

`44.0 J//s`

Text Solution

Verified by Experts

`110 - 100 = i , R`
`210 - 200 = i_(2) R`
from (i) and (ii)
`i_(2) = i_(1) = 4 J//s`
