JEE Advanced is one of the most prestigious engineering entrance exams in India, and it covers a wide range of topics in physics. The syllabus for the physics section of JEE Advanced is extensive and includes various topics, including gravitation and celestial mechanics. Let's discuss in detail whether you can expect questions from these topics in the exam.

Gravitation:
Gravitation is an important topic in the physics section of JEE Advanced. It deals with the study of the gravitational force and its effects on celestial bodies. Here are some key points regarding the inclusion of gravitation in the exam:

1. Syllabus: Gravitation is a part of the JEE Advanced syllabus. The syllabus is determined by the exam conducting authority, and it clearly mentions the topics that candidates need to study. Gravitation is specifically mentioned in the syllabus, indicating that questions related to this topic can be expected in the exam.

2. Weightage: The weightage of each topic in the exam is not specified, but considering the importance of gravitation in the field of physics, it is likely to have a significant weightage. Therefore, candidates should thoroughly study this topic to secure a good score in the exam.

Celestial Mechanics:
Celestial mechanics is another important topic that deals with the motion of celestial bodies, such as planets, moons, and satellites. Here's what you need to know about its inclusion in the JEE Advanced exam:

1. Syllabus: Celestial mechanics is not explicitly mentioned in the JEE Advanced syllabus. However, it is a subtopic of mechanics, which is an important part of the syllabus. Mechanics includes the study of various types of motion, including rotational and orbital motion. Since celestial mechanics falls under the umbrella of mechanics, questions related to this topic may be asked in the exam.

2. Previous Year Questions: It is always a good practice to go through previous year question papers to understand the pattern and difficulty level of the exam. While celestial mechanics may not be explicitly mentioned, there might be questions indirectly related to this topic. Therefore, it is important to have a solid understanding of mechanics to tackle such questions effectively.

In conclusion, while gravitation is explicitly mentioned in the JEE Advanced syllabus, celestial mechanics is not explicitly mentioned but falls under the broader topic of mechanics. Therefore, it is advisable for candidates to thoroughly study both gravitation and mechanics to be well-prepared for questions related to these topics in the physics section of the JEE Advanced exam.
