Coulomb’s Law F = kqQr2 relates the force F between two charges q and Q, which are a distance of r units apart. Choose the formula that represents this when solved for k.

Answer 1

Answer:

$f = k \frac{qq}{ {r}^{2} } \: \: \: \: \times {r}^{2} \\ f {r}^{2} = kqq \: \: \div qq$

$\frac{f {r}^{2} }{qq} = k$

this is answer A
