Morning Session ( 9:30 am to 12:30 pm )
The JEE mains is considering one of the most challenging and competitive exams for engineering courses. The National Test Agency is conducting JEE Mains 2019 exam in two slots ( Morning and Forenoon) and it is Computer Based Test which was held from the past 5 days. The JEE Mains 2019- 12th January first slot exam analysis is done by our Entrance360 experts on the basis of the JEE mains Question Paper available at the official website. The official Answer key and Question paper are released now. The Question Paper consisted of 90 questions each and 4 marks for each question. All questions were objective type with the single correct option. The Question paper is divided into 3 sections: Chemistry, Physics, and Mathematics. Each section consisted of 30 questions worth 120 marks. This article involves details such as the Type of Questions, Overall Exam level, Subject-wise exam analysis, Chapter-wise analysis, etc. We suggest you take a printout of the JEE Mains question paper and response sheet to check their answer from the official answer key.
Physics paper was moderate to tough with respect to previous years question papers. The physics section contains 15 easy type questions that were very specific to the chapter. If you have a good understanding of the important concept and you prepare well to apply these concepts in the exam to find the solution without any mistake, then you can easily score around 45 to 50 marks in physics only from these 15 questions in nearly 20-22 minutes. After that, there are 8 questions of medium level, Since they were based on 2-3 concepts from the specific chapter and they contain lengthy calculations to find the solution. But if you carefully read these questions and visualize the given situation in the Questions, then you will get to know about the concepts asked in questions.
You just need to apply these concepts correctly and to do an error-free calculation with the focused mind to get solutions. After that, there are 7 difficulty level questions which were involved in difficult concepts, mixed chapter, and lengthy calculation. Out of these 7 questions, some question has a level of medium to difficult according to students. You have to solve them with patience. But if you stuck in any Question then skip the question and try other questions that are easy. Overall this section was consist of 13 questions from 11th class physics and 17 questions from 12th class physics.
you will see 4 questions from the chapter Experimental skills And from these 4 questions, 3 questions will require knowledge of current electricity which is a class 12th chapter.

The chemistry was Moderate to Easy amongst the three. The questions were a mix of theory and calculations, which ensured that students saved time for the other two sections. This section was numerically oriented in comparison to the other sections. There were 19 questions asked from the 12th standard syllabus and 11 questions from the 11th standard syllabus. This section had 4 difficult questions, 18 moderate questions, and 8 easy questions.

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Two metallic spheres are charged to the same potential. One of them is hollow and another is solid, and both have the same radii. Solid sphere will have lower charge than the hollow one.
Reason R: Capacitance of metallic spheres depend on the radii of spheres.
In the light of the above statements, choose the correct answer from the options given below.
Both and are true and is the correct explanation of
is true but is false
is false but is true 4.
