The plates of a parallel plate capacitor are separated by 5mm. The electric field among them is 4.2 x 10^5 V/m. A proton is released with an initial velocity of zero at the positive plate. Suppose there is a vacuum between the plates.

1. Express the kinetic energy of the proton in eV

2. What is the kinetic energy, in J, when it reaches the negative plate?
