Coulomb's Law: As shown in the figure, charge q1 = 2.2 × 10-6 C is placed at the origin and charge q2 = -3.30 × 10-6 C is placed on the x-axis, at x = -0.200 m. Where along the x-axis can a third charge Q = -8.30 × 10-6 C be placed so that the resultant force on Q is zero?

Fill in the blank(s) with the appropriate word(s).
