Three rods made of the same material and having the same cross-section have been joined as shown in the figure. Each rod is of the same length. The left and right ends are kept at 0 0 C and 90 0 C respectively. The temperature of the junction of the three rods will be
Text Solution
Verified by ExpertsThe correct answer is:
B
T/R = 2(90`– T)/R,
T=60 
where R is thermal resistance of one rod.
