A semi-circular, insulating rod has radius R and lies in the xy-plane. It carries a total charge Q. The center of curvature (i.e., the center of the circle of which this is a part) is at the origin, and the rod itself is in the first and second quadrants. Find the electric field vector produced by this charge distribution at the origin.

a circular ring of charge of radius 1 m lies in the x-y plane and is centered at the origin. Assume also that the ring is in air and carries a density 2rho C/m. A) find the electric potential V AT (0,0,Z) b) Find the corresponding electric field E. (Assume electric field @point have x,y direction because Rho(l) is not constant)
A circular loop of wire, centered at the origin, lies in the xy plane. The loop has a radius of 10.0cm. A cylindrical magnet (radius 0.5 cm and length-5 cm) starts out at rest with its primary axis along the z-axis. The bottom tip of the magnet is a north-pole and is situated at z 8 cm. The magnet is dropped straight down so that it falls north- pole down and it goes straight through the center of the loop....
