PREFACE
In sync with the recent changes in the test pattern and format of JEE Main (Joint Engineering
Entrance), it is my pleasure to introduce Master Resource Book in Physics for JEE Main, for the
Students aspiring a seat in a reputed Engineering College. JEE Main is a gateway examination for
candidates expecting to seek admission in Bachelor in Engineering (BE), Bachelor of Technology
(B.Tech) and Bachelor of Architecture (B.Arch) at Indian Institutes of Information Technology (IIITs),
National Institutes of Technology (NITs), Delhi Technological University and other Centrally Funded
Technical Institutes (CFTIs).
JEE Main is also an examination which is like screening examination for JEE Advanced
(The gateway examination to India's most reputed Technical Institutes, Indian Institutes of
Technology IITs). Only the top 2.2 lacs students passed in JEE Main will be able to attempt
JEE Advanced.
Gradually, the number of students aspiring for the seat in the Engineering College has increased
rapidly in the last 5 Years or so. This year nearly 10 lacs students appeared for JEE Main and only a
few were able to reserve a seat in the college of their choice, so there is a cut throat competition
among the aspirants. Thus, it calls for a systematic mastery of all the subjects of the test with
paramount importance to problem-solving. Most of the books now in the market have become
repetitive with scant respect to the needs of true and effective learning. This book has been
designed to fulfill the perceived needs of the students as such.
—This book comprehensively covers all the topics of JEE Main Physics syllabus. The chapters have
been sequenced according to the syllabus of class 11th & 12th. Each chapter has essential
theoretical discussion of the related concepts with sufficient number of solved examples and
practice problems. In each chapter previous years' questions of AIEEE and JEE Main have been
included to help students know the difficulty levels and nature of questions asked in
competitive exams at this level.
—All types of questions have been included in this book: Single Correct Answer Types and
Numerical Value Questions.
—This is the only book which has its subject matter divided as per class 11th & 12th syllabus.
It is hoped this new effort will immensely benefit the students in their goal to secure a seat in the
prestigious engineering college, and would be convenient to teachers in planning their teaching
programmes. Suggestions for further improvement are welcomed from the students and teachers.
