Teaching Haryana (HPSC) Assistant Professor Mock Test 2025 Physics Thermal Properties of Matter Temperature and heat
If K1 and K2 are the thermal conductivities, L1 and L2 are the lengths and A1 and A2 are the cross sectional areas of steel and copper rods respectively such that
\(\frac{K_2}{K_1}=9, \frac{A_1}{A_2}=2, \frac{L_1}{L_2}=2\)
. Then, for the arrangement as shown in the figure, the value of temperature T of the steel-copper junction in the steady state will be
