A conducting rod carrying a total charge of +8.00 C is bent into a semicircle of radius R = 34.0 cm, with its center of curvature at the origin (see figure below). The charge density along the rod is given by = ₀ sin(), where is measured clockwise from the +x axis. What is the magnitude of the electric force on a 1.00-C charged particle placed at the origin?
