1) A small particle has charge -3.80 μC and mass 2.10×10−4 kg. It moves from point A, where the electric potential is VA = 190 V, to point B, where the electric potential VB = 920 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 5.60 m/s at point A. a) What is its speed at point B?
