Consider two rods of same length and different specific heats , conductivities and area of cross-sections and both having temperature and at their ends. If rate of loss of heat due to conduction is equal, then :-

Answer: (1)

Solution

The rate of heat conduction is . Both rods have the same length and the same end temperatures and , so equal rates give $ =
