Homework Help: Physics

A point charge q = -2.41 nC is initially at rest adjacent to the negative plate of a capacitor. The charge per unit area on the plates is 4.67 μC/m2 and the space between the plates is 6.53 mm. What is the potential difference between the plates?

What is the kinetic energy of the point charge just before it hits the positive plate, assuming no other forces act on it?

here's the first part: deltaV=4.67μC/m2*(d/8.85E-12) and it should be somewhere over 1000 volts. good luck with the second part, I still don't know it.
