Five Equal Negative Charges Are Uniformly Spaced in a Semicircular

Multiple Choice

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,θ​_i) ,where the values of θ​_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.
