Oct 20, 2015 17:53 IST

    Find AIEEE Solved Physics Question Paper of 2012. These questions will help the students to get the idea that how the papers are being set. These questions will also be helpful to practice the physics questions and to check your preparation for the coming JEE(Main) exam. Here students can find the answer as well as the detailed solution of each questions.

    Few sample questions from the Question Paper are given below:

    Q. A coil is suspended in a uniform magnetic field with the plane of the coil parallel to the magnetic lines of force. When a current is passed through the coil, it starts oscillating; it is very difficult to stop. But if an aluminium plate is placed near to the coil, it stops. This is due to

    (a) development of air current when the plate is placed

    (b) induction of electrical Charge on the plate

    (c) shielding of magnetic lines of force as aluminium is a paramagnetic material

    (d) electromagnetic induction in the aluminium plate giving rise to electromagnetic damping

    Q. Two electric bulbs marked 25 W-220 V and 100 W-220 V are connected in series to a 440 V supply. Which of the bulbs will fuse?

    (a) Both

    (b) 100 W

    (c) 25 W

    (d) Neither

    Q. Resistance of a given wire is obtained by measuring the current flowing in it and the voltage difference applied across it. If the percentage errors in the measurement of the current and the voltage difference are 3% each, then error in the value of resistance of the wire is

    (a) 6%

    (b) zero

    (c) 1%

    (d) 3%

    Q. This question has Statement I and Statement II Of the four choices given the statements, choose the one that describes the two statements.

    Statement I Davisson-Germer experiment established the wave nature of electrons.

    Statement II If electrons have wave nature, they can interfere and show diffraction.

    (a) Statement I is false, Statement II is true

    (b) Statement I is true, Statement II is false

    (c) Statement I is true, Statement II is true; Statement II is the correct explanation for Statement I

    (d) Statement I is true, Statement II is true; Statement II is not the correct explanation of Statement I

    Q. A radar has a power of 1 kW and is operating at a frequency of 10 GHz. It is located on a mountain top of height 500 m. The maximum distance upto which it can detect object located on the surface of the earth (Radius of earth = 6.4 X 106 m) is

    (a) 80 km

    (b) 16 km

    (c) 40 km

    (d) 64 km

    Q. A Carnot engine, whose efficiency is 40%, takes in heat from a source maintained at a temperature of 500 K. It is desired to have an engine of efficiency 60%. Then, the intake temperature for the same exhaust (sink) temperature must be

    (a) Efficiency of Carnot engine cannot be made larger than 50%

    (b) 1200 K

    (c) 750 K

    (d) 600 K

    Q. This question has Statement I and Statement II. Of the four choices given after the statements, choose the one that best describes the two statements.

    If two springs S1 and S2 of force constants k1 and k2, respectively are stretched by the same force, it is found that more work is done on spring S1 than on spring S2.

    Statement I If stretched by the same amount, work done on S1, will be more than that on S2.

    Statement II k1 < k2

    (a) Statement I is false, Statement II is true

    (b) Statement I is true, Statement II is false

    (c) Statement I is true, Statement II is true; Statement II is the correct explanation for Statement I

    (d) Statement I is true, Statement II is true; Statement II is not the correct explanation of Statement I
