Nature of (Strong) Nuclear Force

What is the (Strong) Nuclear Force? The Nuclear force is the force that holds nucleus of an atom together. It can act between both neutrons and protons. It is the strongest among all the fundamental forces in nature. Yet, it only works at extremely short distances. Protons and neutrons are made up of further fundamental particles known as Quarks. The force that exists between such quarks to create stable neutron and proton structures is known as Strong Nuclear Force/Interaction, while the force that exists between such neutrons and protons to create stable nuclear configurations is known as Nuclear force or Residual nuclear force. So how does the nuclear force vary with distance? It is most powerful at distances of around 1 fm. From distances of around 1 - 2.5 fm, it decreases exponentially. For distances greater than 2.5 fm, it is almost negligible. And, finally, for distances less than 0.8 fm, it reverses in sign and suddenly becomes repulsive in nature. This is necessary to avoid collapse of the nuclei. If the nuclear force was not repulsive at extremely short distances, the particles would collapse into themselves. One of the first successful models to explain the mechanism of how such a force works was first given by Hideki Yukawa, in what is now known as the Meson Theory of Nuclear Forces. ▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱ Support💖  / dibyajyotidas   Donate🤝🏻https://paypal.me/FortheLoveofPhysics Telegram - https://t.me/FortheLoveofPhysicsYT ▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱▱ NUCLEAR AND PARTICLE PHYSICS - Series : •••••••••••••••••••••••••••••••••••••••••• 1) What is Nuclear Physics? ►    • What is Nuclear Physics? (LECTURE SER...   2) Nuclear Size / Radius ►    • Nuclear Size / Radius   3) Quantization of Angular Momentum ►    • What is Quantization of Angular Momen...   4) Nuclear Spin and Angular Momentum ►    • Nuclear Spin and Angular Momentum   5) Nuclear Magnetic Moment ►    • Nuclear Magnetic Moment   6) Binding Energy of Nucleus & BE Curve ►    • What is Nuclear Binding Energy? (and ...   7) Parity of Wave function ►    • What is Parity of a Wave function? (O...   8) Symmetric & Anti symmetric Wave func ►    • Symmetric and Anti-symmetric Wave fun...   9) Liquid Drop Model of Nucleus ►    • Liquid Drop Model of Nucleus ( Bindin...   10) Corrections to Liquid Drop Model ►    • Corrections to Liquid Drop Model / Se...   11) NZ Graph (& Maximizing BE) ►    • What is NZ Graph? | Maximizing Bindin...   12) Fermi Energy of Nucleus ►    • Fermi Energy of Nucleus (Derivation)   13) Fermi Gas Model of Nucleus ►    • Fermi Gas Model of Nucleus   14) Shell Model of Nucleus ►    • Shell Model of Nucleus   15) Nature of (Strong) Nuclear Force) ►    • Nature of (Strong) Nuclear Force   16) Alpha, Beta & Gamma Decay ►    • Alpha, Beta & Gamma Decay [Complete D...   17) Gamow's Theory of Alpha Decay ►    • Gamow's Theory of Alpha Decay AND Gei...   18) Gamow's Theory (DERIVATION) ►    • [DERIVATION ] Gamow's Theory of Alpha...   19) Q Value and KE of Alpha Decay ►    • Q-Value | KE of Alpha Decay (Kinematics)   20) Beta Decay & Neutrino Hypothesis ►    • Beta Decay & Neutrino Hypothesis !! (...   21) Radioactive Decay Law ►    • What is Radioactive Decay? Half Life ...   22) Nuclear Cross Section ►    • Nuclear Cross Section !!   23) Interaction of Nuclear Radiation with Matter ►    • Interaction of Nuclear Radiation with...   24) What is Cherenkov Radiaton? ►    • The Physics of Cherenkov Radiation   25) Nuclear Detectors ►    • Nuclear Detectors - Ionization Chambe...   26) Geiger Muller Counter ►    • What is a GM Counter? - Geiger Muller...   27) Scintillation Detector ►    • What is a Scintillation Detector?   28) Semiconductor Detectors ►    • What are Semiconductor Detectors?   29) What are Accelerators? ►    • What are Accelerators? + Electrostati...   30) Van de Graaff Generator ►    • Van de Graaff | Tandem & Pelletron Pa...   31) Linear Accelerator ►    • Linear Particle Accelerator (Principl...   32) Cyclotron ►    • Cyclotron (Principle, Construction, W...   33) Synchrotron ►    • Cyclotron & Synchrotron (Particle Acc...   34) Betatron ►    • Cyclotron & Synchrotron (Particle Acc...   35) Fission & Fusion ►    • Nuclear Fission and Fusion | What rol...   36) Proton-Proton & CNO Cycle ►    • Proton Proton Cycle & CNO Cycle   37) Meson Theory of Nuclear Forces ►    • Meson Theory of Nuclear Forces & Esti...   ••••••••••••••••••••••••••••••••••••••••••• NUCLEAR PHYSICS - PLAYLIST    • Nuclear Physics   ••••••••••••••••••••••••••••••••••••••••••• #NuclearPhysics mage Attribution : 1) Nucleus Marekich [CC BY-SA 3.0 (https://creativecommons.org/licenses/...)], from Wikimedia Commons 2) Quark structure - neutron No machine-readable author provided.
