Vector field

  1. Jun 20, 2005 #1
    A vector field is difined by A = f(r)r.

    a) show that f(r) = constant/r^3 if divergence A equal to zero.

    b) show that curl A is alway equal to zero

    i think you mean, find a divergence and curl in a spherical coordinates. vector r is represent r, theta and phe
