At what position is the net electric field that is produced equal

  1. Two charges are separated by 1.0 m. Q1 has a negative charge of 4.2 µC and Q2 has a positive charge of 1.4 µC. At what position is the net electric field that is produced by both Q1 and Q2 equal to zero?

    Extra Credit: If a +5.0 µC charge is placed at this position, what force would act on it as a result of Q1 and Q2?
