Chapter 22, Problem 14P

In Fig. 22-41, particle 1 of charge q₁ = − 5.00q and particle 2 of charge q₂ = +2.00q are fixed to an x axis. (a) As a multiple of distance L, at what coordinate on the axis is the net electric field of the particles zero? (b) Sketch the net electric field lines between and around the particles.
