QUESTION ABOUT PLOT VECTOR FIELD

I am running Mathematica 2.1, and having trouble using Plot Vector Field when trying to plot electrostatic fields with singularities of type 1/r or 1/r^2 at the origin of coordinates. Often when the plot goes near the origin, the programme answers "Floating Point Error" and the PC goes out of service. Is there any way of getting a plot in this case?, or do I have to accept only graphics in regions far from the origin? Can you help me, please? Thanks in advance. Rubin Carabio. Buenos Aires.
