An electron is unrestricted from rest at a point in an evacuated region of space at which the electric potential is 5.0 volts. No force except the force of the electric field characterized by the electric potential under discussion acts on the electron. What is the kinetic energy of the electron while it is at a location where the electric potential is 16 volts?
