Calculate the electric force between 2 electrons that are 5.3 x 10^-11 m apart (electron charge = -1.6 x 10^-19 C)

I'm using the equation for Coulomb's Law: F = K (q1 q2)/d^2

(-1.6 x 10^-19)(-1.6 x 10^-19) /

5.3 x 10^-11 m ^2

Am I even on the right track???????

(9*10^9)(-1.6 x 10^-19)(-1.6 x 10^-19) /

(5.3 x 10^-11)^2
