(a) Two charges are placed on the x-axis: one is placed at x = 3 m and the other is at x = - 3 m. The magnitude of both charges is 2.3 µC but the blue one (at x = - 3 m) is positive while the red one (at x = + 3 m) is negative.

What are the x - and y-components of the electric field at (x, y) = (0 m, + 4 m) ?

(b) Now the positive and negative charge switch places. The magnitude of the charges is still 2.3 µC where the blue one (now at x = + 3 m) is positive and the red one (now at x = - 3 m) is negative.

What are the x - and y-components of the electric field at (x, y) = (0 m, + 4 m) ?

(c) Now both charges (still at x = - 3 m and x = + 3 m) are positive. The magnitude of both charges is still 2.3 µC.

What are the x - and y-components of the electric field at (x, y) = (0 m, + 4 m) ?

(d) Finally, both charges (still at x = - 3 m and x = + 3 m) are negative. The magnitude of both charges is still 2.3 µC.
