Question

In a rectangular coordinate system, a positive point charge Q1 = 6.00 nC is placed at the point x = + 0.150 m, y= 0, and an identical point charge, Q2, 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
