Frequently Asked Questions:-

1. Is electrostatics important for JEE Advanced?

Yes, electrostatics is important in JEE Advanced, because it is a foundation for several concepts in physics.

Questions about Coulomb's law, electric fields, potential, and capacitance are ubiquitous. Besides, questions can even test your know-how regarding conductors' and dielectrics' behavior within electric fields.

2. Can I get IIT with 75 marks in JEE Advanced?

For 75 marks, it may be difficult to obtain admission into premier IITs since JEE Advanced cutoff tends to require a higher mark, especially when admission into popular streams is sought. However, the cutoff varies from year to year, depending on the level of difficulty and the number of students. For open category students, scores are normally expected to be more than 150-200 in order to obtain a seat in an IIT.

3. Is it easy to score 150 in JEE Advanced?

Scoring 150 in JEE Advanced is possible, but it must be achieved strategically. Master important topics, solve a lot of problems, and learn how to handle time during the exam. Difficulty level in JEE Advanced varies annually, but a consistent preparation schedule on the basis of topics like mechanics, electrostatics, and modern physics can be effective.

4. Which is the toughest chapter in JEE Advanced Physics?

Optics, Modern Physics, and Electrostatics are considered to be the most difficult chapters in JEE Advanced Physics by many students. Optics needs a clear concept of waves. Modern Physics checks your quantum mechanics and atomic model knowledge. Electrostatics also has conceptual problems in electric fields and potential.
