Hello Aspirants. Welcome to Online General Knowledge section in Affairs cloud, which is important for all the competitive exams. We have created Some questions related to General Science(Physics) !!

  1. Which one of the following denotes inertial mass ?
    1.M/V
    2.w/g
    3.F/a
    4.v×d
    5.None of these
    Answer –3.F/a
    Explanation :
    Inertial mass measures an object’s resistance to being accelerated by a force => F/a

  2. Ball pen function is based on the principle of ……………….
    1.Boyle’s law
    2.Surface tension
    3.Gravitational force
    4.Viscosity
    5.None of these
    Answer – 2.Surface tension
    Explanation :
    Ball pen function is based on the principle of Surface tension. Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible.

  3. …………….. is the most basic property of liquids
    1.Viscosity
    2.Fluidity
    3.Elasticity
    4.Volume Conservation
    5.None of these
    Answer – 4.Volume Conservation
    Explanation :
    Volume Conservation is the most basic property of liquids

  4. Newton postulated his corpuscular theory of light on the basic of
    1.Rectilinear propagation of light
    2.Colour of thin films
    3.Newton’s rings
    4.Disperson of white lights
    5.None of these
    Answer – 1.Rectilinear propagation of light
    Explanation :
    Newton’s corpuscular theory of light on the basic of  Rectilinear propagation of light
    Light consists of very tiny particles known as “corpuscular”.
    These corpuscles on emission from the source of light travel in straight line with high velocity and When these particles enter the eyes, they produce image of the object or sensation of vision.

  5. Which of the following color of light will travel with minimum speed through glass ?
    1.Green
    2.Red
    3.Violet
    4.Yellow
    5.None of these
    Answer – 3.Violet
    Explanation :
    Red travels the fastest and Violet travels the slowest

  6. Total internal reflection can occur when light passes from …………………………..
    1.Rarer to denser medium
    2.Irrespective of medium of travel
    3.Travel from one medium to other medium
    4.Denser to rarer medium
    5.None of these
    Answer – 4.Denser to rarer medium
    Explanation :
    Total internal reflection is a phenomenon that occurs when light travels from a more optically dense medium (or a medium with higher refractive index ) to a less optically dense one (lower index ), such as glass to air or water to air.

  7. The Spectrum of Carbon monoxide is …………………
    1.Band Spectrum
    2.Line Spectrum
    3.Continuous
    4.Linear Spectrum
    5.None of these
    Answer – 1.Band Spectrum
    Explanation :
    All of the numerous band spectra formerly attributed to carbon are due probably to carbon compounds

  8. Which one of the following is a vector quantity ?
    1.Electric Field Intensity
    2.Electric Charge
    3.Charge Density
    4.Electric Potential
    5.None of these
    Answer – 2.Electric Charge
    Explanation :
    Electric charge is a vector quantity because doesn’t ‘point’ in a physical direction in space.

  9. Hydrogen bomb is based on ………………….
    1.Controlled fission
    2.Uncontrolled fission
    3.Uncontrolled fusion
    4.Controlled fusion
    5.None of these
    Answer – 3.Uncontrolled fusion
    Explanation :
    hydrogen bomb or H-bomb, weapon deriving a large portion of its energy from the nuclear fusion of hydrogen isotopes

  10. Crompton effect is associated with which one of the following ?
    1.X-rays
    2.β rays
    3.Positive rays
    4.γ rays
    5.None of these
    Answer – 1.X-rays
    Explanation :
    In a Crompton effect a beam of monochromatic X-rays is scattered by a light element
