A Very Small 4 $8.0 \mathrm {~m} / \mathrm { s }$

question 93

Short Answer

A very small 4.8-g particle carrying a charge of +9.9 ?C is fired with an initial speed of $8.0 \mathrm {~m} / \mathrm { s }$ directly toward a second small 7.8-g particle carrying a charge of + $5.2 \mu \mathrm { C }$ 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)
