The image above shows some of electric field lines due to 3 poin charges along the vertical axis. All 3 charges have the same magnitude. A. What are the signs of the 3 charges? Explain reasoning. B. At what points is the magnitude of the electric filed the smalles? Explain reasoning. C. Explain how the fielsd produced by each individual point charge combine to give a small net field at this point or points.
E points away from positive charges. Magnitude ought to be indiated by the spacing: narrower spacing, Higher E.
