Two particles each have a mass of 6.0 × 10-3kg. One has a charge of +5.0 × 10-6 C, and theother has a charge of -5.0 × 10-6 C. They areinitially held at rest at a distance of 0.80 m apart. Both are the nreleased and accelerate toward each other. How fast is eachparticle moving when the separation between them is one-third itsinitial value?
Each particle is moving at a speed of 9.7 m/s.
