In a rectangular coordinate system, a positive point charge q = 8.00 nC is placed at the point x= 0.250 m, y = 0, and an identical point charge is placed at x= -0.250 m, y = 0. Find the x and y components and the magnitude and direction of the electric field at the following points.
a) Find the x and y components and the magnitude and direction of the electric field at x= 0.500 m, y=0.
