JEE Main 2016 Physics Paper Analysis

Last Updated - April 09, 2017

JEE Main 2016 is an abbreviation of Joint Entrance Exam- to grab admissions in various fields of Under Graduate (UG) Engineering Courses in the Top Ranking Institutes. This exam is conducted every year at All India Level by Central Board of Secondary Education (CBSE). There are 2 papers in JEE Main Exam. For engineering aspirants, JEE Main Paper 1 is must, which contains 3 sections: Physics, Chemistry and Mathematics. All these sections have equal number of questions and are equally marked. The total number of questions in each section is 30 and each question carries 4 marks. The JEE Main exam is an objective type exam, which has 4 multiple choices. Out of which only 1 is correct. This exam has negative marking too. The correct choice will fetch you the 4 marks and the wrong choice will lose you 1 mark.

This article will provide the fresh idea on the JEE Main Physics Paper Analysis by covering its all aspects like the chapter wise marks distribution, number of questions asked from +2 and +1 level, difficulty level of the exam, important topics to be prepared and many more.


IIT JEE Main 2016 Physics Chapter Wise Marks Distribution

Following table will fetch you the idea in brief about the number of questions asked and the weightage of the Physics Chapters for JEE Main Exam. From the past years of paper analysis, the number of questions asked in JEE Main Entrance Exam, it can be said that there is no fixed number of questions from particular topic. The number of questions fluctuates every year. The weightage column shows the total marks of questions asked and the percentage weightage of the topic.

Number of Questions asked from Class 11th & Class 12th in 2015, 2014  and 2013

NCERT Syllabus of Class 11th and Class 12th of CBSE Board has everything that is asked in the JEE Main Exam. Out of the total 90 questions, there is a probability of 3-4 questions that may come in the JEE Main Exam out of the syllabus. From the availability of data, it can be seen that the number of questions asked from +1 and +2 were equal in 2014 and 2015. This is not fixed that how many questions can be asked from both the classes. The fluctuations may vary every year. Following graph shows the number of questions asked from Class 11thand Class 12thin the past three years 2013, 2014 and 2015-

Difficulty Level of Questions Asked in Previous Years

The total number of questions asked in Physics Section in 2015 were 30, out of which only 5 questions were marked difficult, 17 questions were marked moderate and the remaining 8 questions were easy. The difficulty level of the exam has dropped from previous year, as shown by available data in graphical representation.But according to the survey, JEE Main aspirants prove that the physics section in 2015 was very tough as compared to the other sections.

Important Topics of Physics in JEE Main 2016 Exam

This section will get you know the idea regarding the topics to be prepared well according to the priority, like the most important chapters that carry nearly 6% to 10% weightage, the important chapters that carry the weightage of 4% to 6% and at last, the least important topics that carry the nearly 3% weightage or less. The most important topic have to be prepared very well and must be through to them as this section carries large number of questions in the JEE Main Exam. Least important topics must not be left aside but to be prepared as these can help you to fetch more marks and hence increase your ranking. So do well all the topics-

  • Most Important Topics- Oscillations & Waves, Rotational Motion, Electrostatics, Atoms & Nuclei, Current Electricity, Laws of Motion and       Magnetic Effects of Current & Magnetism.
  • Important Topics- Kinematics, Thermodynamics, Work Energy and Power, Optics, Electronic Devices, Properties of Solids & Liquids,Electromagnetic Waves
  • Less Important Topics- Electromagnetic Induction, Physics & Measurement, Communication System, Kinetic Theory of Gases, Alternating,Current, Dual Nature of Matter & Radiation and Gravitation.

Changes Made in the Last Years

As if, we see in the changes made in the recent years, there are no such changes in the exam pattern. If there are changes made, it will be updated on the official website. However there are changes in the difficulty level of the exam as compared to the last 10 years of paper analysis. From starting, the difficulty level has come down. There are chances of lowering the cut off as compared to last year. And it may vary by some reasons like lack of interest in engineering, lower number of JEE aspirants. As there are different sets in JEE Main Exam, so difficulty level of different subjects were varied. Physics is that section in the JEE Exam which may come in form of more numerical as compared to theoretical questions. So it must be focused well.


Sample Questions of JEE Main Physics Paper

Q.1 As an electron makes a transition from an excited state to the ground state of a hydrogen – like atom/ion:

(1) kinetic energy, potential energy and total energy decrease

(2) kinetic energy decreases, potential energy increases but total energy remains same

(3) kinetic energy and total energy decrease but potential energy increases

(4) its kinetic energy increases but potential energy and total energy decrease

Q.2 A red LED emits light at 0.1 watt uniformly around it. The amplitude of the electric field of the light at a distance of 1 m from the diode is:

(1) 2.45 V/m

(2) 5.48 V/m

(3) 7.75 V/m

(4) 1.73 V/m

Q.3 A train is moving on a straight track with speed 20 ms-1 . It is blowing its whistle at the frequency of 1000 Hz. The percentage change in the frequency heard by  a person standing near the track as the train passes him is (speed of sound = 320 ms-1 ) close to :

(1) 12 %

(2) 18 %

(3) 24 %

(4) 6 %

Q.4 Distance of the centre of mass of a solid uniform cone from its vertex is z0. If the radius of its base is R and its height is h then z0 is equal to:

(1) 3h/4

(2) 5h/8

(3) 3h2/8R

(4) h2/4R

Q.5 A particle of mass m moving in the x direction with speed 2v is hit by another particle of mass 2m moving in the y direction with speed v. If the collision is perfectly inelastic, the percentage loss in the energy during the collision is close to

(1) 50%

(2) 56%

(3) 62%

(4) 44%
