The discussion focuses on the cancellation of vertical and horizontal components of electric fields due to symmetry in charge arrangements. Specifically, when charges are symmetrically placed above and below a center point, their vertical components cancel each other out. In contrast, if the charge arrangement is not symmetrical, such as in a 1/4 arc configuration, both x and y components will be present. The key takeaway is that symmetry dictates the presence or absence of these components in electric field calculations.

I don't know what you mean. It's not the size of the arc, it's the symmetry.ToonBlue said:
The symmetry will be about a line from the point O to the center of the arc. Since that's not along the x or y axis, there will be an x and y component.ToonBlue said:
