<div><span class="Apple-style-span" style="font-family: arial,sans-serif; font-size: 13px; border-collapse: collapse;">I have used the pst-electricfield package to draw the field of two positive point charges. However, the code below produces
<div>a line connecting the two charges. I do not think that it should be like that, but more like in <a target="_blank" href="http://dev.physicslab.org/Document.aspx?doctype=3&filename=Electrostatics_PointChargesElectricFields.xml" style="color: rgb(17, 37, 8);">http://dev.physicslab.org/<wbr>Document.aspx?doctype=3&<wbr>filename=Electrostatics_<wbr>PointChargesElectricFields.xml</a><wbr>.</div>
<div><br>
</div>
<div>Am I mistaken? If I am not, is there a way of correcting it?</div>
