Question
The length and radii of two rods made of same material are in the ratio 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 :-
Options
A.1 : 3
B.4 : 3
C.3 : 2
D.8 : 9
Solution
