A) \[90{}^\circ C\]
B) \[85{}^\circ C\]
C) \[70{}^\circ C\]
D) \[50{}^\circ C\]
Correct Answer: C
Solution :
Key Idea: In the steady state, the rate of flow of heat in both the conductors will be the same. Taking the two conductors with same cross-section area A, joined in series, with same length d Let H be heat flow through this combination and \[\theta \] is temperature of common surface. In steady state rate of flow of heat is same hence,You need to login to perform this action.
