LITTLE KNOWN FACTS ABOUT ELECTRIC E BIKES.

Take into account the Distinctive situation of the favourable position charge q at the origin. To estimate the prospective due to q in a distance r from your origin relative to the reference of 0 at infinity (remember that we did a similar for possible energy), Allow (P = r) and (R = infty), with (dvec l = dvec r = hat r dr) and use (vec E = frac k
