An electron is placed in a region with a 1010 V/m electric field directed in the positive x-direction. The electron escapes this region after traveling 14.0 cm. What is the kinetic energy of the electron? What is the particle's velocity? Will a proton placed at the same initial position and traveling through a similar 14.0 cm path acquire the same amount of kinetic energy? Will the proton experience the same change in velocity? Why or why not?

The proposed setup is a pair of conducting metal grids arranged parallel and connected to a battery which establishes the electrical potential difference.
