This revised version of the book consists of material covering the latest syllabus prescribed by CSIR–UGC/GATE as well as other competitive examinations of national level. This book is remarkable for its comprehensive coverage.
One aspect in each area of the problems spans a wide spectrum of topics. The problems themselves are remarkable for their versatility in applying the physical laws and principles, their up-to-date realistic situations and their scanty demand on mathematical skills.
The solutions presented generally just provide a guidance to solving the problems, rather than step by step manipulation, and leave much to the students to work out for themselves, of which much is demanded of the basic knowledge in physics. Thus, the book would provide an invaluable complement to the text books. International units are used whenever possible, but in order to conform to some of the problems, Gaussian units are also used. This in fact would give the student broader training and wider experience. Great pains have been taken to trace the logical steps from the first principles to the final solutions. These efforts hopefully will enhance the value of the book to students and teachers alike.
