PREFACE“Don’t follow your dreams; chase them!”- a quote by Richard Dumbrill is perhaps the most pertinent for onewho is aiming to crack entrance examinations held after std. XII. We are aware of an aggressive competition astudent appearing for such career defining examinations experiences and hence wanted to create books thatdevelop the necessary knowledge, tools and skills required to excel in these examinations.ontentFor the syllabus of MHT-CET 2020, 80% of the weightage is given to the syllabus for XIIth standard whileonly 20% is given to the syllabus for XIth standard (with inclusion of only selected chapters). Since there is noclarity on the syllabus for MHT-CET 2021 till the time when this book was going to be printed and taking thefact into consideration that the entire syllabus for std. XIIth Science has always been an integral part of MHTCET syllabus, this book includes all the topics of std. XIIth Physics.We believe that although the syllabus for Std. XII and MHT-CET is aligned, the outlook to study the subjectshould be altered based on the nature of the examination. To score in MHT-CET, a student has to be not justgood with the concepts but also quick to complete the test successfully. Such ingenuity can be developedthrough sincere learning and dedicated practice.Having thorough knowledge of theory, derivations and their applications is a prerequisite for beginning withMCQs on a given chapter in Physics. Students must know formulae, conversion factors, units and dimensionsof physical quantities involved in the chapter. Physics is conveyed using mathematics, therefore, studentsshould study essential mathematical concepts such as trigonometric functions, identities, derivatives andintegration rigorously. They should befriend ideas of tangent, slope, area under the curve and nature of variousplots and their equations to resolve graphical intricacy of Physics. It should be kept in mind that every singleline of text has potential of generating several MCQs.CAs a first step to MCQ solving, students should start with elementary questions. Once a momentum is gained,complex MCQs with higher level of difficulty should be practised. Questions from previous years as well asfrom other similar competitive exams should be solved to obtain an insight about plausible questions.The competitive exams challenge understanding of students about subject by combining concepts fromdifferent chapters in a single question. To figure these questions out, cognitive understanding of subject isrequired. Therefore, students should put in extra effort to practise such questions.ePromptness being virtue in these exams, students should wear time saving short tricks and alternate methodsupon their sleeves and should be able to apply them with accuracy and precision as required.plSuch a holistic preparation is the key to succeed in the examination!To quote Dr. A.P.J. Abdul Kalam, “If you want to shine like a sun, first burn like a sun.”mOur Triumph Physics book has been designed to achieve the above objectives. Commencing from basicMCQs the book proceeds to develop competence to solve complex MCQs. It offers ample practice of recentquestions from various competitive examination. While offering standard solutions in the form of concise hints,it also provides Shortcuts and Alternate Methods. Each chapter ends with an Evaluation test to allow selfassessment.Features of the book presented on the next page will explicate more about the same!SaWe hope the book benefits the learner as we have envisioned.The journey to create a complete book is strewn with triumphs, failures and near misses. If you think we’venearly missed something or want to applaud us for our triumphs, we’d love to hear from you.Please write to us on: mail@targetpublications.orgA book affects eternity; one can never tell where its influence stops.From,PublisherEdition: FirstBest of luck to all the aspirants!

Therefore, target 1 has three target drops, i.e., target 1-A-1, target 1-B-1 and target 1-C-2. In this manner we can enumerate all possible target drops from target information. From source and target information we can set all possible assignments, and each of them is composed of a source and sequence of target drops, called a target drop set .
