 Preface

This book Principles of Physics, Grade Xtis an outcome of the overwhelming response that we had from our valued readers, teachers, and students from different colleges, guardians, and well-wishers. At this juncture, we extend our heartfelt gratitude to all. 

The contents of the book have been revised and improved by the need for the new syllabus prescribed by the Curriculum Development Center (CDC), Sanothimi, Bhaktapur, Nepal. We hope this edition fulfills the requirement of a complete syllabus. The authors have ceaselessly worked hard to make this book a complete textbook of physics for grade XI. Each lesson has been properly scrutinized and its classroom implication has seen well assessed, We believe this endeavor will further ensure students’ success in competitive examinations of different kinds along with qualifying themselves for college/university degrees.

This book is expected to deserve significance because of its following special features:

(ii) Self-test numerical problems presented in the book enable the students to understand the lessons thoroughly,

(iii) The book comprises multiple exercises, numerical problems, very short, short, and long question answers which can help the students develop scientific skills.

(iv) Various objective questions are given and they will be helpful for the students Preparing for engineering as well as medical examinations, and many other competitive examinations of universities,

(v) Various questions and problems are included from University Physics of Sears and Zemansky, and Advanced Level Physics of Nelson and Parker,

(vi) Review and summary, key formulae, and useful information of each chapter are separately given in the tabular form,
