A small particle has charge -5.00µC and mass 2.00 X 10-4 kg. It moves from point A, where the electric potential is VA = + 200 V, to point B, where the electric potential is
VB = +500 V. The electric force is the only force acting on the particle. The particle has speed 5.00 m/s at point A. What is its speed at point B? Is it moving faster or slower at B than at A? Explain.
