Describes the electrostatic force between two point charges.

$$ F = k_e \frac{q_1 q_2}{r^2} $$

Where $k_e \approx 8.99 \times 10^9 \, \text{N}\cdot\text{m}^2/\text{C}^2$.

The vector field surrounding an electric charge.

$$ \mathbf{E} = k_e \frac{q}{r^2} \mathbf{\hat{r}} $$

ForceF = kq₁q₂/r²

E-FieldE = kq/r²

PotentialV = kq/r

EnergyU = kq₁q₂/r
