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-

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

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

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
