Coulomb's law
(static electrical force relation)
Coulomb's law states that the force between static-electrically-charged
objects is proportion to the product of their charges
and inversely proportional to the square of their intervening distance:
q1q2
F = ke ————
r²
- F - force: electric force aka Coulomb force.
- ke - Coulomb's constant: 8.99 × 109 N m2 C-2 (i.e., Newton meter2 / Coulomb2 ).
- q1, q2 - the two charges.
- r - distance between the two charges.
This is similar to gravitational force, both being inverse square laws,
but in this case, the force repels if the charges are the same
polarity and attracts if they are opposite polarity. This law and
force are equivalent to Gauss's law, one of
Maxwell's equations.
The force is relevant to atomic physics, e.g., the attraction between
electrons and the nucleus, and nuclear physics, e.g., the repulsion
between two nuclei.
