Statement-2: When a beam of highly energetic neutrons is incident on a tungsten target, no `X` -rays will be produced.
Statement-2: Neutrons do not exert any electrostatics force on electrons or nucleus of an atom

Statement 1: When a beam of highly energetic neutrons is incident on a tungsten target, no X-rays will be produced. Statement 2: Neutrons do not exert any electrostatic force on electrons or nucleus of an atom.

Statement-1: Gamma rays are more energetic than X-rays. Statement-2: Gamma rays are of nuclear origin but x-rays are produced due to sudden deceleration of high energy electrons while falling on metal of high atomic number.

Statement: The neutrons are better initiater of nuclear reactions than protons, deutrons, deutrons or alpha- particles. Explanation: Neutrons being uncharged particles, not exert repulsive forces form nucleus.

Statement-I : When X-ray incident on metal, the ejection of electron shows the particle nature of X-ray. Statement-II : X-ray is positively charged particle.

Highly energetic electrons are bombarded on a target of an element containing 30 neutrons. The ratio of radii of nucleus to that of Helium nucleus is 141//3 . The atomic number of nucleus will be.

Statement-1 If the accelerating potential in an X-ray tube is increased, the wavelength of the characterstic X-rays do not change. because Statement-2 When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.
