"The book contains a variety of problems, selected from the books by renowned authorities on the subject and also from different engineering entrance examinations. Although the book presupposes the knowledge of +2 level physics from some standard text, nevertheless a brief summary of necessary definitions and formulae is given at the beginning of each chapter. Unlike many other books on this subject, derivation of different formulae is altogether avoided, except in certain cases where it was found necessary. This book differs from most of the other books available in the market in one respect: whereas in the existing books the problems have been solved by the direct application of the formulae without explaining the underlying principle involved, this book lays emphasis on both the basic principle involved and the technique required to solve a problem. The solution provided in this book for any given problem is far more superior, in terms of comprehensiveness and giving insight to the students, to those provided in the other existing books. Moreover, all the steps leading to the answer have been fully explained. "The book contains more than 1000 solved problems and approximately an equal number of practice exercises for the students, and hence, will be extremely useful for the students preparing for JEE-IIT and equivalent examinations."
