Explain Gravatational , Electromagnetic , Strong Nuclear and Weak Nuclear Forces

#GravitationalForce:
a) The gravitational force is the mutual force of attraction between any two objects by
virtue of their masses. It is a universal force.
b) It plays an important role in the formation and evolution of stars, galaxies and
galactic clusters.
#ElectromagneticForce:
a) For a fixed distance, electromagnetic force between protons is 10^36 times the
gravitational force between them.
b) Electromagnetic force is the base for the structure of atoms and molecules.
c) Gravity is always attractive, while electromagnetic force may be attractive or
repulsive.
#StrongNuclearForce:
a) The strong nuclear force binds protons and neutrons in a nucleus.
b) This is strongest of all fundamental forces and about 100 times stronger than
electromagnetic force.
c) It is charge independent and acts equally between Proton - Proton, Neutron -
Neutron, and
Proton -Neutron.
d) Its range is very small (10^–15m).
e) It is responsible for the stability of nuclei.
#WeakNuclearForce:
a) This force appears only in certain nuclear processes such as the β − decay.
b) These are weaker than the strong nuclear and electromagnetic forces, but stronger
than gravitational forces.
c) Their range is very small (10^–16 m).
