An isolated free electron is traveling through an electric field from some initial point where it's coulombic potential energy per unit charge (voltage) is 17KJ/C and velocity = 93Mm/s to some final point where it's coulombic potential energy per unit charge is 6KJ/C. Determine the charge in velocity of the electron . Neglect gravitational forces. What is the solution please.
