The top left diagram below shows a 1-C positive charge placed in
a uniform external electric field. The electric field in which the
charge is placed is represented by field lines (drawn in red), and
the resulting electric force on the charge is represented by the
blue vector. Suppose the 1-C charge is removed, and is replaced, in
turn, by each of the charges shown in the other three diagrams
below. Assuming that the external electric field remains the same,...

An electric field can be created by a single charge or a distribution of charges. The electric field a distance r from a point charge q' has magnitude {E}=k\frac{|q'|}{r^2}. The electric field points away from positive charges and toward negative charges. A distribution of charges creates an electric field that can be found by taking the vector sum of the fields created by individual point charges. Note that if a charge q is placed in an electric field created by...

You will explore the electric fields of charged wires and circular loops and the fields of current-carrying versions of these same objects, so this question is meant to give you a reference point with which to compare and contrast the two types of fields. 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?...
