Ya sure I will get the JEE Mains exam paper so that you can start preparation for exam easily.

Here is the exam paper
Choose the correct statement :
(1) In frequency modulation the amplitude of the high frequency carrier wave is made to vary in proportion to the amplitude of the audio signal.

(2) In frequency modulation the amplitude of the high frequency carrier wave is made to vary in proportion to the frequency of the audio signal.

(3) In amplitude modulation the amplitude of the high frequency carrier wave is made to vary in proportion to the amplitude of the audio signal.

(4) In amplitude modulation the frequency of the high frequency carrier wave is made to vary in proportion to the amplitude of the audio signal.

An arc lamp requires a direct current of 10 A at 80 V to function. If it is connected to a 220 V (rms), 50 Hz AC supply, the series inductor needed for it to work is close to :
(1) 0.044 H
(2) 0.065 H
(3) 80 H
(4) 0.08 H

The temperature dependence of resistances of Cu and undoped Si in the temperature range 300-400 K, is best described by :
(1) Linear increase for Cu, exponential decrease for Si.
(2) Linear decrease for Cu, linear decrease for Si.
(3) Linear increase for Cu, linear increase for Si.
(4) Linear increase for Cu, exponential increase for Si.

Arrange the following electromagnetic radiations per quantum in the order of increasing energy :
A : Blue light B : Yellow light
C : X-ray D : Radiowave.
(1) C, A, B, D
(2) B, A, D, C
(3) D, B, A, C
(4) A, B, D, C

Half-lives of two radioactive elements A and B are 20 minutes and 40 minutes, respectively. Initially, the samples have equal number of nuclei. After 80 minutes, the ratio of decayed numbers of A and B nuclei will be :
(1) 1 : 4
(2) 5 : 4
(3) 1 : 16
(4) 4 : 1
