Please see attached document. The following is a discussion of the vector calculations of Coulomb's law. If you indeed want to relate this to a time scale, then in stead of using static r values in your calculations, you make them time-dependent variables.

A positive charge of 3.0 X 10 to -6 C is pulled on by two negative charges. One, -2.0 X 10 to -6 C is 0.05m to the north and the other, -4 X 10 to -6C is 0.030m to the south. What totla force is exerted on the positive charge?View Full Posting Details
