SELECTED QUETIONS AND PROBLEMS IN PHYSICS

This collection of questions and problems in physics is in ­ tended for the students of correspondence courses and evening classes in intermediate colleges and is in accord with the existing curriculum .

The purpose of this book is to teach the students how to solve problems in physics. This should stimulate corre­spondence course students to work independently, encourage them to accumulate an adequate theoretical background, and develop in them the requisite aptitude for practical activity in various branches of the economy.

Each section begins with a brief description of the basic theoretical concepts, laws, and formulas. This provides the maxim um possible help to correspondence course students in
solving problems. A large number of problem s are supplied with detailed solutions and an analysis of the results, while in some cases different approaches are used to solve the same
problem so that the student can discover the most rational form of independent study.

The theoretical material is presented in a lucid form, and most problems are of medium complexity. However, each section contains tougher problem s as well. Their solution requires a broader range of theoretical data, and will fa­cilitate a deeper understanding of the physics course.

In keeping with the existing curriculum, problem s in astronomy have also been included in the collection. Their solution requires the use of a star chart, which is printed on the flyleaf.
