There is a bead of mass m on a rigid, unmoving wire. The wire passes fairly snugly through a hole in the bead: i.e., the bead is strung on the wire. The wire is FRICTIONLESS and there is NO air drag. The wire extends in the horizontal and vertical directions. As one moves along the horizontal direction, the wire rises and falls and even does loops. The wire has multiple maxima and minima and horizontal segments of finite length. The wire goes on and on: it has no ends: it may be closed: i.e., form a continuous loop. The whole system is located on the surface of the Earth—where the only significant gravitational force is that of the Earth. At

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
