A charge of -3.00 nC is located at the origin of an x-y coordinate system, and a charge of 2.00 nC is located on the y-axis at y=4 centimeter.
a. If a third charge of 5.00nC is now located at the point x=3.00 centimeter, y=4.00 centimeter, find what are the x and y components of the total force exerted on the charge by the other two charges?
b. find the magnitude and direction of the total force?
