A small particle has charge -7.30 μC and mass 3.00×10-4 kg. It moves from point A, where the electric potential is V₁ = 300 V, to point B, where the electric potential VB = 900 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 5.10 m/s at point A.
