Two particles each have a mass of 6.4×10−4 kg. One has a charge of +6.1×10−6 C, and the other has a charge of −6.1×10−6 C. They are initially held at rest at a distance of 1.1 m apart. Both are then released and accelerate toward each other. How fast is each particle moving when the separation between them is one-third its initial value? Number Units
