Re: Jee Old Question Paper

Joint Entrance Exam is the first steps to get admission into the top engineering colleges across all over India i.e. IIITs (Indian Institute of Informational technology), NITs(National Institute of technology) and CFTs(Centrally Funded Technical institutes). It is better to know pattern of the exam.

There is a smart way by which you get clear idea about exam pattern i.e. once you solve JEE Main previous year question papers.

PART A PHYSICS


ALL THE GRAPHS/DIAGRAMS GIVEN ARE SCHEMATIC AND NOT DRAWN TO SCALE.
1. The density of a material in the shape of a cube is determined by measuring three sides of the cube and its mass. If the relative errors in measuring the mass and length are respectively 1.5% and 1%, the maximum error in determining the density is :
(1) 2.5%
(2) 3.5%
(3) 4.5%
(4) 6%

2. All the graphs below are intended to represent the same motion. One of them does it incorrectly. Pick it up.
(1)
(2)
(3)
(4)

3. Two masses m1=5 kg and m2=10 kg, connected by an inextensible string over a frictionless pulley, are moving as shown in the figure. The coefficient of friction of horizontal surface is 0.15. The minimum weight m that should be put on top of m2 to stop the motion is :
(1) 18.3 kg
(2) 27.3 kg
(3) 43.3 kg
(4) 10.3 kg

4. A particle is moving in a circular path of radius a under the action of an attractive potential 2

5. In a collinear collision, a particle with an initial speed vo strikes a stationary particle of the same mass. If the final total kinetic energy is 50% greater than the original kinetic energy, the magnitude of the relative velocity between the two particles, after collision, is :

6. Seven identical circular planar disks, each of mass M and radius R are welded symmetrically as shown. The moment of inertia of the arrangement about the axis normal to the plane and passing through the point P is :
(1) 19 MR2 2
(2) 55 MR2 2
(3) 73 MR2 2
(4) 181MR2 2

7. From a uniform circular disc of radius R and mass 9 M, a small disc of radius R 3 is removed as shown in the figure. The moment of inertia of the remaining disc about an axis perpendicular to the plane of the disc and passing through centre of disc is :
(1) 4 MR2
(2) 40 2 MR 9
(3) 10 MR2
(4) 37 2 MR 9

8. A particle is moving with a uniform speed in a circular orbit of radius R in a central force inversely proportional to the nth power of R. If the period of rotation of the particle is T, then :
(1) T∝R 3/2 for any n.
(2) n 2 1 T R + ∝
(3) TR (n+1)/2
(4) TRn/2

9. A solid sphere of radius r made of a soft material of bulk modulus K is surrounded by a liquid in a cylindrical container. A massless piston of area a floats on the surface of the liquid, covering entire cross section of cylindrical container. When a mass m is placed on the surface of the piston to compress the liquid, the fractional decrement in the radius of the sphere, dr r       , is :
(1) Ka mg
(2) Ka 3 mg
(3) mg 3 Ka
(4) mg Ka

10. Two moles of an ideal monoatomic gas occupies a volume V at 278C. The gas expands adiabatically to a volume 2 V. Calculate (a) the final temperature of the gas and (b) change in its internal energy.
(1) (a) 189 K (b) 2.7 kJ
(2) (a) 195 K (b) 2.7 kJ
(3) (a) 189 K (b) 2.7 kJ
(4) (a) 195 K (b) 2.7 kJ

11. The mass of a hydrogen molecule is 3.32 10 27 kg. If 1023 hydrogen molecules strike, per second, a fixed wall of area 2 cm2 at an angle of 458 to the normal, and rebound elastically with a speed of 103 m/s, then the pressure on the wall is nearly :
(1) 2.35 103 N/m2
(2) 4.70 103 N/m2
(3) 2.35 102 N/m2
(4) 4.70 102 N/m
