15. [1pt] For each diagram above, select from
below the picture of the string at the instant of time when the two
pulses overlap completely. E.g., if the answer to 1 is A and the
answer to 2 is G, enter AG. You only have 4

A finite rod of length L has total charge q, distributed uniformly along its length.
Potential of a Finite RodA finite rod of length L has total charge q, distributed uniformly along its length. The rod lies on the x-axis and is centered at the origin. Thus one endpoint is located at (-L/2,0), and the other is located at (L/2,0). Define the electric potential to be zero at an infinite distance away from the rod. Throughout...

Two long wires are oriented so that
they are perpendicular to each other. At their closest, they are
20.0 cm apart. What is the magnitude of the magnetic field at a
point P between them if the top one carries a current of 18.0 A to
the left and the bottom one carries 12.0 A to the right?

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...

Two identical small current carrying loops of wire are oriented along a common axis with the plane of their loops parallel to each other. See Figure EC. The distance between the loops, x, is much larger than the radius of each loop, R. The magnetic dipole moment of each loop is directed parallel to the axis, and the magnetic field...
