Objective Physics?was first published in 1997. Since then it has received overwhelming response from teachers and students all over the country and some places abroad. We have received hundreds of letters appreciating the basic approach to the pres?entation of the subject, and the selection and ordering of problems. The book has been invaluable in the preparation for the Engineering and Medical Entrance Examinations of all Indian Universities and Institutes. Many emotionally charged letters have been written by parents also, mentioning that their wards, who earlier found physics very difficult, could succeed in their chosen entrance examination because they read this book. Nothing can be more satisfying and rewarding for an author.
