Potential Energy: A 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 × 109 N ? m2/C2)
Fill in the blank(s) with the appropriate word(s).
3.0 m
