Electric field due to point charge¶

The strength of the electric field set up by a point charge is linearly proportional to the value of the charge and the square inverse of the distance to it.

Notation:

\(\varepsilon_0\) (epsilon_0) is vacuum_permittivity.

law¶

E = q / d^2 / (4 * pi * epsilon_0)

Latex:: \[E = \frac{1}{4 \pi \varepsilon_0} \frac{q}{d^{2}}\]
