5 SIMPLE TECHNIQUES FOR FIIDO Q1S

Consider the Unique case of a positive stage charge q within the origin. To determine the potential a result of q in a distance r with the origin relative to a reference of 0 at infinity (recall that we did the exact same for potential energy), let (P = r) and (R = infty), with (dvec l = dvec r = hat r dr) and use (vec E = frac kq r^two hat r ).
