A proton (mass = 1.67 x 10-26 kg charge = 1.60 x 10-19 C) is running at a speed of 8.50 x 104 m/s at a point in an evacuated region of space where the electric potential is 35.0 volts. No force however the force of the electric field characterized by the electric potential acts on the proton. The particle moves to a point in the evacuated region of space where the electric potential is 47.0 Volts. What is the speed of a particle at that point in space?
