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.

A

Statement-1 is true, Statement-2: is true, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is true, Statement-2: is true, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is true but statement-2 is false

D

Statement-1 is false, Statement-2 is true

Text Solution

Verified by Experts

The correct Answer is:
D
Neutron will knock out electrons in target leading to production of characterstic X-ray hence statement-1 is false.

Statement 1: Though light of a single frequency (monochromatic light) is incident on a metal, the kinetic energies of emitted photoelectrons are not equal. Statement 2: The energy of electrons just after they absorb photons incident on metal surface may be lost in collision with other atoms in the metal before the electron is ejected out of the metal.

Statement-1:When a planet approches the point which is farthest from the sun, its orbital speed decreases. Statement-2: Work done on the planet by the gravitational force exerted by the sun is negative.

Statement-1: A thin stainless steel needle can lay floating on a still water surface. Statement-2: Any object floats when the buoyancy force balances the weight of the object.

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.

Statement-1: The photoelectrons produced by a monochromatic light beam incident on a metal surface have a spread in their kinetic energies. Statement-2: The work function of the metal varies as a function of depth form the surface.

Statement-1 : The frequency of K_(alpha) X-radiation is greater than K_(beta) for a given target material. and Statement-2 : K_(alpha) radiation is produced when an electron from n = 2 jumps into the vacancy in n = 1 orbit, whereas in K_(beta) radiation the transition takes place from n = 2 to n = 1 .

Statement-1: When cathode rays strike a hard metallic surface highly penetrating radiation is obtained. bacause Statement-2 : The shortest wavelength limit of X-rays produced is inversely proportional to the accelerating voltage.

All nuclei consist of two types of particles- protaon and neutrons. Nuclear force is the strongest froce. Stability of nucleus is determined by the neutron - proton ratio or mass defect or binding energy per nucleus or packing fraction. Shape of nucleus is calculated by quadrupole moment. Spin of nucleus depends on even or odd mass number. Volume of nucleus depends on the mass number. Whole mass of the atom (nearly 99 % ) is centered at the nucleus. Magnetic moment of the nucleus is measured in terms of the nuclear magnetons. The correct statements about nuclear force is/are

The characteristic X-ray radiation is emitted when A. the bombarding electrons knock out electrons from the inner shell of the target atoms and one of the outer electrons falls into this vacancy B. the valance electrons are removed from the target atoms as a result of the collision C. the source of electrons emits a mono energetic bean D. the electrons are accelerated to a fixed energy

Statement-1 : Ultrasonics is the acoustic analogue of ultraviolet radiation Statement-2 : Ultraviolet rays do not produce visual sensations while ultrasonic waves are not heards by the human ear.
