Universal Gravitation

This text book is primarily intended for students who are preparing for the entrance tests of IIT-JEE/NEET/AIIMS and other esteemed colleges in same fields. This text is equally useful to the students preparing for their school exams. Main Features of the Book- 1. In this textual material even a trivial concept is substantialized in this way to make it lucid and easy to grasp. Every concept is given in student friendly language followed by a ladder of illustration and checkpoint questions. The solution of checkpoint is provided with problem solving approach and discussion. 2. Special attention is given to tricky topics (like - applications of Newton's law of gravitation, calculation of gravitational
field from gravitational potential and vice versa, gravitational field and potential due to a continuous mass distribution,
variation in g in a rotatory frame, Gauss's law of gravitation, motion of a satellite, circular motion of a multistar system,
energy consideration and applications of Kepler's laws etc.) so that student can easily solve them with fun. 3. At the end of the theory part, there are miscellaneous solved examples which involve the application of multiple concepts of this chapter. 4. To test the understanding level of students, multiple choice questions, conceptual questions, practice problems with previous years JEE Main and Advanced problems are provided at the end of the whole discussion. Number of dots indicates level of problem difficulty. Straightforward problems (basic level) are indicated by single dot (●), intermediate problems (JEE mains/NEET level) are indicated by double dots (●●), whereas challenging problems (advanced level) are indicated by thee dots (●●●). Answer keys with hints and solutions are provided at the end of the chapte
