Homework Help: A potential V(r) = -k/r^4 A very superficial analysis

  1. Dec 9, 2003 #1
    What are the general features of this potential? Is the particle attracted or repelled? You don't need to perform a mathematical analysis, but qualitatively, what is the general shape of the orbits? Assume energy is positive. What happens if angular momentum is zero?

    Curved toward the center, but not closed (the're only closed for [itex]V \sim r^{-1}[/itex], Kepler motion). I guess they look like a pattern produced by a spirograph.
    The body will fall into the center. From there, it will not be possible to calculate the further motion because of the singularity.
