Question

coulombs law $f = k\frac{qq}{r^{2}}$ relates the force $f$ between two charges $q$ and $q$, which are a distance of $r$ units apart. solve the formula for $k$.

Explanation:

Step1: Comenzar con la ley de Coulomb

$F = k\frac{qQ}{r^{2}}$

Step2: Despejar k

Multiplicamos ambos lados por $r^{2}$: $Fr^{2}=kqQ$. Luego dividimos ambos lados por $qQ$ para obtener $k = \frac{Fr^{2}}{qQ}$.

Answer:

$k = \frac{Fr^{2}}{qQ}$
