edit: I see that my title is incorrect. This isnt between charges, it is between a charge and a point, sorry about that. The problem: Find the magnitude of the electrostatic force that works on a point 3 meters from q1. q1=3μC My attempts: Feq1=1/(4πε0)*(q1/r) r=3m 1/(4πε0)=8.988x109 Feq1=8.988x109*(3x10-6/3)=89.9kN As far as I can tell, this is the way it should be done, but the force seems pretty large... Is there something that I am missing? Or is this actually correct?
