The previous year question paper of JEE Advance or Joint Entrance Examination Advanced is as follows: Consider the partition to be rigidly fixed so that it does not move. When equilibrium is achieved, the final temperature of the gases will be (A) 550 K (B) 525 K (C) 513 K (D) 490 K Now consider the partition to be free to move without friction so that the pressure of gases in both compartments is the same. Then total work done by the gases till the time they achieve equilibrium will be (A) 250 R (B) 200 R (C)100 R (D) −100R When d≈a but wires are not touching the loop, it is found that the net magnetic field on the axis of the loop is zero at a height h above the loop. In that case (A) current in wire 1 and wire 2 is the direction PQ and RS, respectively and ℎ ≈ a (B) current in wire 1 and wire 2 is the direction PQ and SR, respectively and ℎ ≈ a (C) current in wire 1 and wire 2 is the direction PQ and SR, respectively and ℎ ≈ 1.2a (D) current in wire 1 and wire 2 is the direction PQ and RS, respectively and ℎ ≈ 1.2a JEE Advanced Question Paper ![]() ![]() ![]() ![]() |
