Temperature difference of \( 120^{\circ} \mathrm{C} \) is maintained between two ends of a uniform \( \operatorname{rod} \mathrm{AB} \) of length \( 2 \mathrm{~L} \).
\( \mathrm{P} \)
Another bent rod PQ, of same cross-section as AB and length \( \frac{3 L}{2} \), is connected across \( \mathrm{AB} \) (See figure).
In steady state, temperature difference between \( \mathrm{P} \) and \( \mathrm{Q} \) will be close to:
(1) \( 45^{\circ} \mathrm{C} \)
(2) \( 75^{\circ} \mathrm{C} \)
(3) \( 60^{\circ} \mathrm{C} \)
(4) \( 35^{\circ} \mathrm{C} \)
