Calculate electrostatic force magnitude between two point charges in vacuum. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
F = k_e |q_1q_2|/r^2

Charges are stationary points in vacuum; material permittivity and charge distributions are excluded.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
