Special Homework Assignment #7
A very long wire carrying a current I has a perfectly
circular loop of radius R in it (the wire is continuous
and is insulated so there is no contact where the wire
crosses over itself). Determine the magnitude an
An insulating rod of
length L has a total
charge of +Q uniformly
spread along its length.
The rod lies along the xaxis with its left end
located at x = a.
Special Homework Assignment #4
(a) Find the electric potential at the origin.
Special Homework Assignment #2
In each box shown below, draw electric field lines in the region around the objects. Assume the
boxes are far from each other.
Positive point charge
Two insulating spheres coated with positive surface charge
An isolated capacitor of unknown
capacitance C has been charged to a
potential difference of 100 V. When the
charged capacitor is then connected in
parallel to an initially uncharged 10 F
capacitor ( stands for 10-6), the voltage
across the com

An infinitely long insulating cylindrical shell has an inner radius a, an outer radius b, and an
unknown uniform positive charge density (charge per unit volume) distributed in the region
between r = a and r = b.
Special Homework Assignment #9
An optical fiber consists of a glass core with index of refraction ng = 1.52 surrounded by a
coating with index of refraction nc = 1.25. The fiber is submerged in water
