Learning Goal: To understand how to calculate forces between charged particles, particularly the dependence on the sign of the charges and the distance between them. Coulomb's law describes the force that two charged particles exert on each other (by Newton's third law, those two forces must be equal and opposite). The force F21 exerted by particle 2 (with charge q₂) on particle 1 (with charge q₁) is proportional to the charge of each particle and inversely proportional to the square of the distance r between them: F21 = 9291 21. where k = 4TCO and 21 is the unit vector pointing from particle 2 to particle 1. The force vector will be parallel or antiparallel to the direction of f 21, parallel if the product 91 92 > 0 and antiparallel if q1 q2 <0; the force is attractive if the charges are of opposite sign and repulsive if the charges are of the same sign.
