The lengths and radii of two rods made of same material are in the ratios 1:2 and 2:3 respectively. If the temperature difference between the ends for the two rods be the same, then in the steady state, the amount of heat flowing per second through them will be in the ratio
View answer and explanation
Correct option: C
Option C () is correct because the heat flow rate is proportional to the area and inversely proportional to the length, considering the ratio of radii and lengths.
