==Key Stage 5==
===Meaning===
'''Coulomb's Law''' states that the [[force]] between two [[Electrical Charge|charged]] [[particle]]s is [[Directly Proportional|directly proportional]] to the [[Product (Maths)|product]] of their [[Electrical Charge|charges]] and [[Inversely Proportional|inversely proportional]] to the square of the [[distance]] between them.
===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.
===Equation===
<math>F=\frac{1}{4 \pi \epsilon_0} \frac{q_1q_2}{r^2}</math>
Where:
<math>F</math> = The [[force]] acting between the [[Electrical Charge|charged particles]]
<math>epsilon_0</math> = The [[Permittivity of Free Space]] (<math>8.85\times10^{-12})
<math>q_1</math> = The [[Electrical Charge|charge]] on one [[particle]].
<math>q_2</math> = The [[Electrical Charge|charge]] on the other [[particle]].
<math>r</math> = The [[distance]] between the [[particle]]s.
: The definition can be derived from the equation by considering
<math>\frac{1}{4 \pi \epsilon_0}</math> is a constant k.
<math>\frac{q_1q_2}</math> is the product of the [[Electrical Charge|charges]].
<math>\frac{1}{r^2}</math> is the the [[Inversely Proportional|inverse]] of the square of the [[distance]].
Therefore
<math>F=k\frac{q_1q_2}{r^2}</math>
