HC Verma Vol-1 Chapter-11 Solutions: Gravitation (Detailed Step-by-Step Answers)

Chapter 11 of HC Verma’s Concepts of Physics Vol-1, titled “Gravitation”, is a fundamental chapter that explores one of the most important forces in nature — gravity. This chapter is vital for students preparing for JEE Main, JEE Advanced, NEET, and other competitive exams as it builds a strong base for celestial mechanics, orbital motion, and gravitational potential. In this write-up, we provide detailed, step-by-step solutions to all the questions in Chapter 11, helping students learn and apply the concepts with clarity and confidence.

Overview of Chapter 11: Gravitation

This chapter covers:

• Newton’s law of universal gravitation

• Acceleration due to gravity and its variation

• Gravitational potential and potential energy

• Orbital motion of satellites

• Escape velocity and binding energy

• Kepler’s laws of planetary motion

These topics are not only important from a theoretical standpoint but also carry high weightage in both board exams and competitive entrance tests. The numerical and conceptual problems in HC Verma’s Gravitation chapter help students develop a deeper understanding of gravitational forces and motion under central forces.
