Five equal negative charges are uniformly spaced in a semicircular arc of radius r0 with its center at the origin. The charges positions in polar coordinates are given by (r0, ?i), where the values of ?i are 0°, 45°, 90°, 135°, and 180°. At the position (x, y) = (r0, –r0) in the 4th quadrant, which statement best describes the direction of the resulting electric field?
a. The direction is that of a 4th quadrant angle.
b. The direction is that of a 3rd quadrant angle.
c. The direction is that of a 1st quadrant angle.
d. The direction is that of a 2nd quadrant angle.
