As you want I am here providing you the sample paper of the JEE Main Exam may this helpful to you.

Sample questions :
1. The pressure that has to be applied to the ends of a steel wire of length 10 cm to keep its length constant
when its temperature is raised by 100°C is :
(For steel Young’s modulus is 2 × 1011 N m−2 and coefficient of thermal expansion is 1.1 × 10−5 K−1)
(1) 2.2 × 107 Pa (2) 2.2 × 106 Pa (3) 2.2 × 108 Pa (4) 2.2 × 109 Pa

3. A bob of mass m attached to an inextensible string of length l is suspended from a vertical support. The
bob rotates in a horizontal circle with an angular speed ω rad/s about the vertical. About the point of
suspension :
(1) angular momentum changes in direction but not in magnitude.
(2) angular momentum changes both in direction and magnitude.
(3) angular momentum is conserved.
(4) angular momentum changes in magnitude but not in direction.


The current voltage relation of diode is given by I = (e1000V/T − 1) mA, where the applied voltage V is in
volts and the temperature T is in degree Kelvin. If a student makes an error measuring ± 0.01 V while
measuring the current of 5 mA at 300 K, what will be the error in the value of current in mA?
(1) 0.5 mA (2) 0.05 mA (3) 0.2 mA (4) 0.02 mA


An open glass tube is immersed in mercury in such a way that a length of 8 cm extends above the mercury
level. The open end of the tube is then closed and sealed and the tube is raised vertically up by additional
46 cm. What will be length of the air column above mercury in the tube now?
(Atmospheric pressure = 76 cm of Hg)
(1) 38 cm (2) 6 cm (3) 16 cm (4) 22 cm

A parallel plate capacitor is made of two circular plates separated by a distance of 5 mm and with a
dielectric of dielectric constant 2.2 between them. When the electric field in the dielectric is 3 ×
104 V/m, the charge density of the positive plate will be close to :
(1) 3 × 104 C/m2 (2) 6 × 104 C/m2 (3) 6 × 10−7 C/m2 (4) 3 × 10−7 C/m2
