1.) Consider a very long, straight wire of uniform positive charge density. In the space below, describe the electric field of the wire. In particular, what direction does it point? Does its strength depend on position? If so, how? Note any symmetries of interest. 2.) Use the understanding of electric fields you developed above to deduce the electric field at the center of a circular loop of wire (radius R) with the same positive uniform charge density. Specifically, is it:...
An infinitely long cylindrical conductor with radius R has a uniform surface charge density ơ on its surface. From symmetry, we know that the electric field is pointing radially outward: E-EO)r. where r is the distance to the central axis of the cylinder, and f is the unit vector pointing radially outward from the central axis of the cylinder. 3.

Find the electric field a distance s from an infinitely long straight wire that carries a uniform line charge λ. You must use two methods, one is standard methods (do the integration from -oo to oo along the wire), another is Gauss law, then you will know why Gauss law is so convenient by comparison.
