Electrostatic force
= Electrostatic force
{title2=$\mathbf F=q\mathbf E$}
The <electric force> exerted by a time-independent <electric field>. For a <point charge>, the external field excludes its own singular self-field. The <method of images> evaluates conductor-induced forces by the image field at the physical charge's position; the fictitious images need not be physical charges in the conductor interior.
