CONDUCTION

JEE Main 2015 Guidance › Thermal physics questions › CONDUCTION

three rods of identical cross sectional area and made of the same metal form the sides of an isosceles triangle ABC . right angled at B . The points A and B are maintained at temperatures T and √2T respectively . in the steady state ,the temperature of ponit C is T_C. Assume that only heat conducton takes place . find the ratio T_C/T .

heat flow from A to B = heat flow from A to C + heat flow from C to B

simplifying u will get

(âˆš2T - T )/a = (Tc - T)/âˆš2a + (âˆš2T - Tc )/a

u will get Tc = T ..
and this is also correct logically ...
