A small particle has charge `-5.00muC` and mass `2.00 xx 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,
