Homework Help: Very quick question about notation of vector fields

  1. May 14, 2009 #1
    this is a very quick question. my teacher wants me to prove that
    ((kq)/(sqroot(x^2+y^2+z^2))) (x,y,z) is conservative. by this does it mean that

    or does it she mean that

    Basically im asking if that (x,y,z) is being distrubuted or its just acting as the (i,j,k) itself Thank you very much
    Edit oops, forgot the ^3 power in the denominator. But you guys get the point

    The second one is correct.

    It essentially corresponds to the electrostatic field of a point charge at the origin.
