If we imagine completing the circular arc, we can place the origin at the center of the circle. Calculate the electric field vector at the origin due to the charged arc of wire. Assume that the wire is in the xx$-$yy plane and that it extends from $=0$$=0$ to $=1\mathrm{.}2$$=1\mathrm{.}2$ radians, where is the angle with the positive xx$-$axis.
