A charge of -3.00 nC is placed at the origin of an x-y coordinate system, and a charge of 2.00 nC is placed on the y-axis at y=4.00cm.
a. If a third charge of 5.00nC is now placed at the point x=3.00cm, y=4.00cm, what are the x and y components of the total force exerted on the charge by the other two charges?
b. What are the magnitude and direction of the total force?
