Two point charges are placed on the x axis as follows: charge q1=+4 nC is located at x=0.2m, and charge q2=+5nC is located at x=-0.3m (that is negative 0.3m). What are the magnitude and the direction of the net (resultant) force exerted by these two charges on a negative point charge q3=-0.6nC located at the origin>? (k=8.99x10? N*m²/C²)
