A small particle has charge -4.30 μC and mass 2.00×10-4 kg. It moves from point A,
where the electric potential is VA = 260 V, to point B, where the electric potential
VB = 960 V is greater than the potential at point A. The electric force is the only
force acting on the particle. The particle has a speed of 4.60 m/s at point A.

Two particles each have a mass of 6.1 x 10-2 kg. One has a charge of +5.0 x 106 C, and the other has a charge of -5.0 x 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?
