===About Coulomb's Law===
: '''Coulomb's Law''' can be used to calculate the [[magnitude]] of the [[force]] acting between two [[Electrical Charge|charged]] point [[particle]]s.
: '''Coulomb's Law''' has a similar form to [[Newton's Law of Universal Gravitation]] in that both are given with a constant multiplied by a product of some physical property ([[Electrical Charge|charge]] and [[mass]]) and [[Inversely Proportional|inversely proportional]] to the square of the [[distance]] between [[particle]]s.
===Equation===
<math>F=\dfrac{1}{4 \pi \epsilon_0varepsilon_0} \dfrac{q_1q_2}{r^2}</math>
Where;
<math>F</math> = The [[force]] acting between the [[Electrical Charge|charged particles]]
<math>\epsilon_0varepsilon_0</math> = The [[Permittivity of Free Space]] (<math>8.85\times10^{-12}Fm^{-1}</math>)
<math>q_1</math> = The [[Electrical Charge|charge]] on one [[particle]].
<math>r</math> = The [[distance]] between the [[particle]]s.
<math>\dfrac{1}{4 \pi \epsilon_0varepsilon_0}</math> is a constantso the left hand side and right hand side are [[proportional]].
<math>q_1q_2</math> is the product of the [[Electrical Charge|charges]].
<math>\dfrac{1}{r^2}</math> is the the [[Inversely Proportional|inverse]] of the square of the [[distance]].
Therefore;
<math>F\propto\fracdfrac{q_1q_2}{r^2}</math>
