The document is an unsolved physics exam paper from 1996 containing multiple choice questions testing concepts in electricity, magnetism, thermodynamics, optics, semiconductors, and acoustics. It includes 5 sections with a total of 25 questions assessing knowledge of topics like electric field distributions, motion of charged objects in magnetic fields, relationships between gas properties and temperature, image formation with lenses and mirrors, charge carriers in materials, and harmonic frequencies in open and closed pipes. The questions are presented with diagrams and require selecting one or more correct answers from the options provided.

1. IIT JEE –Past papersPHYSICS- UNSOLVED PAPER - 1996

2. SECTION – IMultiple correct Answers type In each part of the question four alternatives are given of which one or more alternative(s) is (are) correct. Select the correct alternative(s) and write down the corresponding letter(s) a, b, c, d in your answer book against the sub-question number. In your answer the sequence of the sub question marks should be the same as in the question paper. For each subqeustion marks will be awarded only if all the correct alternative and no wrong alternative are selected.
