The temperature of the two ends A and B ...

The temperature of the two ends `A` and `B` of a rod of length `25cm` and circular cross section are `100^(@)C` and `0^(@)C` respectively In the steady state, find the temperature at a point `10cm` from the end `B` (ifnore loss of heat from curved surface of the body) ?

A

`60^(@)`C

B

`80^(@)`C

C

`90^(@)`C

D

`10^(@)`C

Text Solution

Verified by Experts

The correct Answer is:
D
From the equation, `theta/x = (Deltat)/(t)`
Given, `t_(1) = 100^(@)`C, l=25 and `pi`=10cm
`theta/10 = (100-0)/(25) rAr theta/10 = 4 rArr theta = 40^(@)`C
