Four identical rods which have thermally insulated lateral surface are joined at point O. Points A,B,C and D are connected to furnace maintained at constant tempertures. If the heat flows into the junction O from A at the rate of 2J/s and from B at 4J/s and flows out towards C is 8J/s. Chosse the correct relation.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BSL_XI_RT_P1_E01_545_Q01.png" width="80%"
