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 = 2⁹1 21. where k=¹ 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 91 920 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. Figure particle 0 particle 1 particle 2 2 of 3 > Part B (Figure 2)Now add a third, negatively charged, particle, whose charge is -q2 (particle 2).
