L are parallel to each other and the y-axis, and are located in the xy plane as shown.
Now assume that the line charge I has a linear charge density where A is a constant. Surface Charge Charge is distributed over the surface of a circle of radius a lying in the xy plane with origin at the center. The surface density is given in cylindrical coordinates by where A is a constant. Find the force produced by this charge distribution on a point charge located on the z-axis. Volume Charge A volume charge distribution has a spherically symmetric shape described by for and zero elsewhere.
