In a rectangular coordinate system a positive point charge q = 6.00 X 10-9 C is placed at the point x = + 0.150 m, y = 0, and an identical point charge is placed at x = -0.150 m, y = 0. Find the x- and y-components, the magnitude, and the direction of the electric field at the following points:
(a) The origin;
(b) X = 0.300 m, y = 0;
(c) X = 0.150 m, y = -0.400 m;
(d) X = 0, y = 0.200m.
