1. The problem statement, all variables and given/known data Determine the point (other than infinity at which the electric field is zero. There is a diagram that has 2 charged particles along the x axis separated by a distance of 1.00m. The charged particle on the right is -2.50μC and the charged particle on the left is +6.00μC. 2. Relevant equations The equation to be used is the one for Electric Fields: E=Ke(q/r2) r(hat) 3. The attempt at a solution I understand how to use the Electric Field equations by plugging in all the values, but how do I determine the distance r in the equation. Where is the Electric field located in space?
