An electron is moving in the direction of a uniform electric
field. What happens to the potential energy of the electron? Is the
electron moving to a location of lower or higher potential?
a.potential energy increases, higher potential.
b.potential energy increases, lower potential.
c.potential energy decreases, higher potential.
d. potential energy decreases, lower potential

An electron is initially at rest in a uniform electric field
having a strength of 1.95 × 106 V/m. It is then released
and accelerated by the presence of the electric field.
What is the change in the electron’s kinetic energy, in
kiloelectron volts, if it travels over a distance of 0.25 m in this
field?
Over how many kilometers would it have to be accelerated in the
same electric field to increase its kinetic energy by 65 GeV?
