Question

In a rectangular coordinate system, a positive point charge q = 6.00 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 and the magnitude and 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 = 0.200 m.
