It has been 2 days that the JEE Main 2019 paper 1 exam has started, there are a few important topics noted from which the questions are being asked in the exam so far. As per the analysis form both the shifts of April 08 and 09, 2019, the important topics from each section have been reported by the students and they are as follows:
Physics
Most of the questions were asked from the topics like Self conductors, EM waves, mechanics and optics. Also, more questions from class 11th were seen in comparison to class 12th. The questions were found to be tough. In most of the shifts, the Physics section remained the most difficult one as per the students. There were many numerical and practical based questions in the exam.
Few questions asked in the exam are:
Q. A resistor with a resistance of 200 ohms has one of its color red. If that color is changed to green then what will be the new resistance.
Q. Starting from rest a particle is moving along x-axis. the variation force with the position is shown in the figure. Find the kinetic energy of the particle when it is at x=3m.
Q. A rope of length ‘l’, mass M is kept on a smooth surface such that (1/n)th part of it is hanging from the surface. Find work done to lift rope on the surface.
Q. A long current carrying wire having current I1 and a square loop of side carrying current I2 are lying in the plane. Find the force on loop due to circle

Chemistry
In chemistry, there were many questions from Organic chemistry and physical chemistry. There a few questions from the s,p and f block too. However, the chemistry part remained the easiest section in all the shifts of April 08, 09, 2019.
Few questions asked in the exam are:
Q. When Diborane (B2H6) reacts with O2 and H2O independently, then the products formed are?
Q. The correct order of hydration enthalpies of Li+, Na+, K+, Rb+, Cs+
Q. Arrange in increasing order of oxidation state of the following: N2O, NO, NO2, N2O3, N2O5
Q. Fluoride is present in which ore?

Mathematics
The mathematics section was found to be moderate to easy in all the shifts in these 2 days. There were questions mostly from trigonometry, 3D, coordinate geometry, and complex numbers, parabola and hyperbola.
Few questions asked in the exam are:
Q. How many 9 digit number can be formed using the digits 1,1,2,2,2,2,3,4,4 such that odd numbers occur at even places?
Q. If sides of a triangle are in A.P. and the largest angle is double the smallest angle, then find the ratio of the sides?
Q. If (1+m2)x2 – 2(1+3m)x + (1+8m) = 0. The number of integral value(s) of m for which this equation has no solution is?
