MHT CET 2026 Physics question
Consider two rods 1 and 2 of same length.. They have different specific heats (, ), thermal conductivities (, ) and area of cross-section (, ) respectively. Both the rods have temperatures (, ) at their ends. If their rate of loss of heat due to conduction is equal then
Answer: (B)
Solution
The rate of heat conduction is . Both rods have the same length and the same end temperatures , , so equal rates give
