Verified by Experts
Yes, nucleons (protons and neutrons) are fundamental particles.
To resolve two objects placed at a distance d, the wavelength `lambda` of the probing signal must be less than d.
So to detect separate parts inside a nucleon the electron must have a wavelength less than `10^(-16)`m.
Also,
`lambda=h/p`
Kinetic energy,
`K.E. =pc = (hc)/lambda=(6.93 xx 10^(-34) xx 3 xx 10^(8))/(1.6 xx 10^(10) xx 10^(-15)) eV`
or `K.E. = 10^(9)eV = 1 GeV`

Assuming the radius of a nucleus to be equal to R=1.3 A^(1//3)xx10^(-15)m . Where A is its mass number, evaluate the density of nuclei and the number of nucleons per unit volume of the nucleus. Take mass of one nucleon =1.67xx10^(-27)kg
Making use of the tables of atomic masses, find: (a) the mean binding energy per one nucleon in O^(16) nucleus (b) The binding energy of neutron and an alpha-particle in a B^(11) nuclues.
A proton is bombarded on a stationary lithium nucleus. As a result of the collision, two alpha -particles are produced. If the direction of motion of the alpha -particles with the initial direction of motion makes an angles cos^-1(1//4) , find the kinetic energy of the striking proton. Given, binding energies per nucleon of Li^7 and He^4 are 5.60 and 7.06 MeV, respectively. (Assume mass of proton ~~ mass of neutron).
A mercury arc lamp provides 0.10 W of UV radiation at a wavelength of lambda = 2537Å (all other wavelenghts having been absorbed by filters). The cathode of photoelectric device (a photo-tube) consists of potassium and has an effective area of 4cm^(2) . The anode is located at a distance of 1 m from radiation source. The work function for potassium is phi_(0) = 2.22eV . (a) According to classical theory, the radiation from the arc spreads out uniformly in space as spherical wave. What time of exposure to the radiation should be required for a potassium atoms(radius 2 Å) in the anode to accumulate sufficient energy to eject a photo-electron? (b) What is the energy of a single photon from the source? (C) What is the flux of photons(number per second) at the cathode? To what saturation current does this flux correspond if the photo-conversion efficiency is 5% (i.e. if each photon has a probability of 0.05 of ejecting an electron). (d) what is the cutt off potential V_(0) ?
The existence of negatively charged particle in an atom was shown by J.J. Thomson as a result of the studies of the passage of electricity through gases at extremely low pressure known as discharge tube experiments. When a high voltage of the order of 10,000 volts or more was impressed across the electrodes, some sort of invisible rays moved from the negative electrode to the positive electrode these rays are called as cathode rays. Cathode rays travel in straight path in absence of electrical and magnetic field . Cathode rays consist of material part and charged particles? Cathode rays produce X-rays and light is emitted when they strike on ZnS screen. Cathode rays penetrate through thin sheets of aluminium and other metals . They affect the photogenic plate and passes heating effect when they strike on metal foil. The raito of charge to mass i.e charge/mass is same for all the cathode rays irrespective of the gas used in the tube. The existence of positively charged particle in an atom was shown be E. Goldstein. He repeated the same discharge tube experiments by using a perforated cathode. It was observed that when a high potential difference was applied between the electrodes, not only cathode rays were produced but also a new type of rays were produced simultaneoulsy from anode moving towards cathode and passes through the holes or canal of the cathode. These termed as canal rays or anode rays. These rays travel in straight lines and consists of positively charged particles. These rays have kinetic energy and produces heating effect also. The e/m ratio of these rays is smaller than that of electrons. Unlike cathode rays, their e/m value is dependent upon the nature of the gas taken in the tube. These rays produced flashes of light on ZnS screen and can pass throughs thin metal foils. They can produce physical and chemical changes and are capable to produce ionisation in gases.
