Question

Five equal negative charges are uniformly spaced in a semicircular

arc of radius ro with its center at the origin. The charges positions in
polar coordinates are given by (o. 6.), where the values of 0 are 0°,
45°, 90°. 135º. and 180°. At the position (x, y) = (ro, -ro) in the 4th
quadrant, which statement best describes the direction of the
resulting electric field?
The direction is that of a 3rd quadrant angle.
The direction is that of a 2nd quadrant angle.
The direction is that of a 1st quadrant angle.
The direction is that of a 4th quadrant angle.​

Answer 1

The direction is that of a 3rd quadrant angle

Step-by-step explanation:

when you have 2 45 angles it equals to 90 then with the 90 we multiply by 2 due to the 2 adjacent angles equating to 180 which swings it to the 3rd quadrant angle
