Important Topics for JEE MAINS 2016 Physics | Do & Die Topics


JEE Mains 2016 is going conducted in the month of April, 2016. It’s really not possible for some students to prepare the whole syllabus. Teachers also suggests that whatever you study, study it by heart. It doesn’t matter how many topics you have prepared for JEE Main exam but the thing that matters is how many topics you have prepared well.

So if you think that it’s not possible to prepare whole syllabus go with some important topics which are scoring and easy for JEE Main exam. Those who want to prepare the whole syllabus are advised to focus more on some scoring topics that I am going to share in this article.

I have gone through the last ten years question papers of AIEEE/JEE Main and gathers some information about important topics for jee mains 2016 physics section. Below I have mentioned eight topics which are relatively easy and scoring topics.

A table is also designed which provides you the information about the number of question asked in a particular year from these important topics. Eight topics are divided into two parts i.e. “Do and Die topics” and “other important topics”.

Do and Die topics share information about four most scoring topics along with their syllabus. Other important topics provides you the information about remaining four topics.

Do or Die Topics:-

Here are four do and die topics of Physics which carries majority of question in JEE Main exam and it is excepted that that in JEE Main 2016 will have majority of questions from these topics only. This is JEE Advanced 2015 Cut off marks for physics which you can easily clear if you focus on do or die topics.

Category Marks
General Equal to or more than 17
OBC Equal to or more than 16
SC Equal to or more than 9
ST Equal to or more than 9
General-Pwd Equal to or more than 9
OBC-Pwd Equal to or more than 9
SC-Pwd Equal to or more than 9
ST-Pwd Equal to or more than 9

And the amazing fact about these topics is that they are from class 12th syllabus and are relatively easy that chapters of 11th class. Below I have shared about the number of questions asked in particular year from these four topics.

Electrostatics 3 1 3 2 3 4 4 4 5

 

1.) Modern Physics: – The most important topic for jee mains 2016 is Modern Physics. This is only chapter which contains a weightage of more than 16 marks. It is a must chapter for each and every candidate who is preparing for JEE Main exam. Modern Physics also have good weightage in JEE Advanced exam.

The topic is relatively easy and one can easily score good marks in JEE Main physics just by understanding some of the concepts and formulas of Modern Physics. Get to know about the syllabus of Modern Physics for JEE Main 2016.

Mass-energy relation, mass defect, binding energy per nucleon and its variation with mass number, nuclear fission and fusion.

2.) Optics: – Optics is yet another do and die topic for JEE Main 2016. It carries a minimum weightage of 12 marks. If you want to score well in JEE Main then don’t ignore this topic.

It is the second most important topic for jee mains 2016 after modern physics. Get to know about the syllabus from Optics below.

Reflection and refraction of light at plane and spherical surfaces, mirror formula, total internal reflection and its applications, deviation and dispersion of light by a prism, lens formula, magnification, power of lens, combination of thin lenses in contact, microscope and astronomical telescope(reflecting and refracting) and their magnifying powers.

3.) Heat and Thermodynamics: – Heat and Thermodynamics also have a good weightage in JEE Main exam which make this topic among the list of do and die topics. Here is syllabus of Heat and Thermodynamics for JEE Main 2016.

Thermal equilibrium, zeroth law of thermodynamics, concept of temperature. Heat, work and internal energy. First law of thermodynamics. Second law of thermodynamics, reversible and irreversible processes, carnot engine and its efficiency.

4.) Electrostatics: – Electrostatics is the fourth most important topic for jee mains 2016 exam which also carries a good weightage. In 2015 cbse asked total of three questions and it is believed that in JEE Mains 2016 also have minimum of 2 question from Electrostatics.

Electric charges:

Conservation of charge, coulomb’s law-forces between two point charges, forces between multiple charges, superposition principle and continuous charge distribution.

Electric field:
