A point charge Q1 = +6.0 nC is at the point (0.30 m, 0.00 m); a charge Q2 = -1.0 nC is at (0.00 m, 0.10 m),
and a charge Q3 = +5.0 nC is at (0.00 m, 0.00 m). What are the magnitude and direction of the net force exerted on the +5.0-nC charge by the other two charges? (k = 1/4??0 = 9.0 × 109 N ? m2/C2 )
