Physics MCQ DebMukherji,PhD Preface The entrance examinations for almost all the premier engineering colleges of the country are presently in the multiple-choice format. This includes the JEE for the IITs and the AIEEE for the other engineering colleges of excellence. This book is designed as the basic study material in physics for these two tests and various other competitiveexaminations. Most of the problems presented in this book have actually evolved in my classrooms. While guiding students for competitive examinations for close to four decades, I have had to innovate problems to make them think. The sequence of their learning process has been first to grasp the basic concepts, then to correlate the problems with the concepts involved, and finally to get a lot of practicetoachievespeedandaccuracy.Thisbookisasummaryofmy coursematerial. Ihavefounditveryusefultosummarizemostoftheconceptsinto single sentences. One may almost call them the sutras of +2 physics. Many of these one-liners appear in the solutions. The questions have been devised to drill the students in all possible applications of these concepts.Tolimitthesizeofthebook,onlythosequestionshavebeen usedwhichhaveprovedmosteffectiveinmyclassrooms. This book is divided into nine parts. The first seven parts cover both theoretical and experimental physics, topicwise. One separate partisdevotedtomiscellaneousquestionscoveringalmostalltypesof objective questions that may be asked in the major competitive tests. Miscellaneous Questions—1 includes straight-objective questions of both single- and multiple-option-correct types. Miscellaneous Questions—2, 3 and 4 respectively contains assertion–reason-type, linked-comprehension-type and matrix-matching-type questions. The ninth part provides the students with several practice papers including model IIT-JEE test papers, which should help them take mocktestsinafixedtime. Both the IIT-JEE and the AIEEE are based on questions that have only one correct choice. This book, however, has a large number of questions in which more than one answer may be correct. These are the teaching questions and train the students towards the comprehension which IIT-JEE demands. Moreover, these more-than- (iii) one-option-correct objective-type questions are sometimes asked in various tests other than IIT-JEE and AIEEE. Several test papers in the single-choiceformatshouldhelpinthefinalrun-up. I hope that students and teachers will come forward with suggestions for improvements in the book. I thank the personnel in the editorial and production departments at Bharati Bhawan for their untiringeffortsandenthusiasminbringingoutthisbook. Author (iv) To the Students The purpose of this book is twofold—first, to teach you the concepts required to tackle the IIT-JEE and AIEEE, and second, to provide practice material for these and other engineering entrance tests. Therefore, although it is possible to frame a large number of multiple-choicequestions,inthisbookonlythosequestionshavebeen givenwhichteachyouimportantconceptsandshowyouthedifferent ways in which they can be applied. If you master these concepts, you can be reasonably sure of working out any multiple-choice question thatcomesyourway. Some of the questions merit hints and some others, the full solutions. The hints and solutions are a very important part of the book. They will clarify your doubts and train you to think along the correct lines. Concepts and techniques which need special attention are highlighted with the TIP icon. Understand these well, for they havewideapplication. In most parts of the book, the straight-objective questions are divided into two types, approximately in equal numbers. Type 1 questions have only one correct option, whereas type 2 questions can havemorethanonecorrectoption.Inthisbook,thereisnodifference in the level of difficulty between the two types. However, type 2 questions are more demanding as every option has to be examined carefully. Try to reason out why each option is either correct or incorrect. This will teach you to think logically. They will also help you in comprehension-type questions. Look at the solutions to fine-tune yourthinking. You will notice that some questions that have been asked in the previousIITexaminationshavebeenincludedhere.Thisistogiveyou anideaaboutthelevelofdifficultyexpectedatthetests. The IIT entrance examinations of 2007 and 2008 have introduced three new question patterns, viz., linked-comprehension type, assertion–reason type and matrix-matring type. Assuming that future examinations would also include such questions, separate sections andchaptershavebeenaddedtohelpyouprepareforthem. (v) Contents Part 1. Mechanics 1-1–1-158 1.
