I want to be sure I'm using the right formula for this question:
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???????

Physics  Help!!! 
Damon,
You are on the right track but you left out k which is 9*10^9 and you must square the distance
(9*10^9)(1.6 x 10^19)(1.6 x 10^19) /
(5.3 x 10^11)^2
