So I'm trying to figure out the electric field that is acting on a point. This point is .3 m right of a point charge with -2N/C and .8m from a point charge with +4N/C. I've drawn it out, and realize both will have an impact on this object. what the issue I'm having is figuring out a formula to use. I would expect that taking the electric field that the +4N/C charge creates using kq1/r1 and then adding the field the second creates kq2/r2 would then give me the complete field. Would this be correct?
