very small 4.8-g particle carrying a charge of +9.9 C is fired with an initial speed of 8.0 m/s directly toward a second small 7.8-g particle carrying a charge of + 5.2 C. The second particle is held fixed throughout this process. If these particles are initially very far apart, what is the closest they get to each other? (k = 1/4₴0 = 9.0 × 10° N • m2/Cz)
