Two charges, -23 μC and +4.2 μC, are fixed in place and separated by 3.0 m. (a) At what spot along a line through the charges is the net electric field zero? Give the distance of the spot to the positive charge in meters (m). (Hint: The spot does not necessarily lie between the two charges.) (b) What would be the force on a charge of +14 μC placed at this spot? Two charges, -23 μC and +4.2 μC, are fixed in place and separated by 3.0 m.
