hi all
when i take the divergence of:
e = {q/r^2, 0, 0}
i get zero. i remembered to load VectorAnalysis and SetCoordinates to
Spherical.
this is the electric field due to a point charge at the origin. even
though MMA doesn't know maxwell's equations, if we strip all the physical
meaning from this vector field, shouldn't the divergence be something other
than zero at the origin?
thanks!
peter
