## How fast is each particle moving, Physics

Assignment Help:

Two particles each have a mass of 6.7 x10-5kg. One has a charge of +5.0 x 10-6C, and the other has a charge of -5.0 x 10-6C. They are initially held at rest at a distance of 0.68 map art. Both are then released and accelerate toward each other. How fast is each particle moving when the separation between them is one-half its initial value?
