In a rectangular coordinate system, a positive point charge q= 4.50 nC is placed at the point x= 0.170 m, y=0 and an identical point charge is placed at x= -0.170 m, y=0 . Find the x and y components and the magnitude and direction of the electric field at the following points.
Part A: Find the x and y components at x=0.170 m, y= -0.350 m.
Part B: Find the magnitude at x=0.170 m, y= -0.350 m.
Part C: Find the direction of the electric field from the positive x axis.
