Posted by APPRECIATIVE STUDENT on Thursday, January 20, 2011 at 7:38pm.

hi -- thank you for your help before-- that makes sense--
also, im stuck on this: if there is a negative2.5 microcoulomb charge 1 m away from a 6microcoulomb charge, then at what point (other than infinity) is the electric field = zero?
Sorry, i have no idea how to do this, i tried finding F using Kq1q2/ r^2 but im not sure what is next...or if that is even correct..?
