Se modela por la expresión. Coulomb's law describes the strength of the electrostatic force (attraction or repulsion) between two charged objects. Its fuel assembly production became serial in 1965 and automated in 1982. Far enough to the right that the force (due to inverse square of the distance from the 2q charge) will be equal and opposite to the force of the -q charge, with the +2q charge exacting a force in the +x direction and the -q charge exacting an equal but opposite force (-x).10 2.602x10-19 .00×10−6C - 7.
