    Why should student solve Rajasthan Board Previous Years’ Question Papers?

    • To get an idea about the important topics and concepts for upcoming board exams.
    • To analyse your strength and weakness so that you may amend your preparation strategy accordingly.
    • To improve your speed of solving questions.

    Some sample questions from the Rajasthan Board Physics question paper 2017 are given below:


    Question:

    Write the name of fields produced by a moving charged particle.

    Solution:

    Electric and Magnet fields are produced by a moving charged particle.

    Question:

    Define Curie temperature in magnetism.

    Solution:

    The Curie temperature is the transition temperature above which ferromagnetic substances start behaving like paramagnetic substances. It is denoted by Tc.

    Question:

    An electron, an alpha (a) particle and a proton have same kinetic energies. Which one of these particles has largest de Broglie wavelength?

    Solution:

    Rajasthan Board Class 12 Physics

    Since, de Broglie wavelength is inversely proportional to the mass of the particle.

    Hence, electron has the largest de Broglie wavelength because of the smallest mass.

    Question:

    Write the name of any four waves (radiations) produced in electromagnetic spectrum.

    Solution:

    The different waves (radiations) produced in electromagnetic spectrum are Gamma rays, X-rays, Ultraviolet rays, Infrared rays and microwaves.

    Question:

    The focal lengths of an objective lens and eyepiece are 192 cm and 8 cm respectively in a small telescope. Calculate its magnifying power and the separation between the two lenses.

    Solution:

    The focal lengths of an objective lens (fo) and eyepiece (fe) are 192 cm and 8 cm respectively.

    The magnifying power (mp) of the telescope is equal to the ratio of focal lengths of an objective lens and eyepiece.

    Rajasthan Board Class 12 Physics

    The separation (L) between the two lenses is equal to the sum of the focal lengths of an objective lens and eyepiece.

    Question:

    Distinguish between modulation and demodulation.

    Solution:

     The difference between modulation and demodulation are given below:

    MODULATION

    DEMODULATION

    Modulation is the process of varying the parameter of the carrier signal according to message bearing signal.

    Demodulation is the process by which message signal is extracted from the modulated wave.

    The circuit needed for modulation is Modulator

    The circuit needed for demodulation is Demodulator/Detector
