You want AIEEE sample papers for the chemistry so I have attached PDF file for the chemistry subject and I also listed here some question:
1. A particle of mass M and charge Q moving with velocity describe a circular path of radius R when subjected to a uniform transverse magnetic field of induction B. The work done by the field when the particle completes one full circle is (a) R 2 R Mv2 p ÷ ÷ ø ö ç çè æ (b) Zero (c) BQ2pR (d) BQ v2 pR 2. A particle of charge - 16´10-18 coulomb moving with velocity 10ms-1 along the x-axis enters a region where a magnetic field of induction B is along the y-axis, and an electric field of magnitude 104V/m is along the negative z-axis. If the charged particle continues moving along the x-axis, the magnitude of B is (a) 103Wb/m2 (b) 105Wb/m2 (c) 1016Wb/m2 (d) 10-3Wb/m2 3. A thin rectangular magnet suspended freely has a period of oscillation equal to T. Now it is broken into two equal halves (each having half of the original length) and one piece is made to oscillate freely in the same field. If its period of oscillation is T¢ , the ratio T T¢ is (a) 2 2 1 (b) 2 1 (c) 2 (d) 4 1 4. A magnetic needle lying parallel to a magnetic field requires W units of work to turn it through 600. The torque needed to maintain the needle in this position will be (a) W 3 (b) W (c) W 2 3 (d) 2W 5. The magnetic lines of force inside a bar magnet (a) are from north-pole to south-pole of the magnet (b) do not exist (c) depend upon the area of cross-section of the bar magnet (d) are from south-pole to north-pole of the magnet
