A small particle has charge −5.00 μ C and mass 2.00 × 10 −4 kg. It moves from point A , where the electric potential is V A = +200 V. to point B , where the electric potential is V B = +800 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.
