Two identical objects \(A\) and \(B\) are at temperatures \(T_A\) and \(T_B\) respectively. Both objects are placed in a room with perfectly absorbing walls maintained at temperatures \(T\left(T_A>T>T_B\right)\). The objects \(A\) and \(B\) attain temperature \(T\) eventually. Which one of the following is correct statement? 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
