A point charge q = 2.5nC is initially at rest adjacent to the negative plate of

Question:

A point charge q = − 2.5nC is initially at rest adjacent to the negative plate of a capacitor. The charge per unit area on the plates is 4.0μC/m2 and the space between the plates is 6.0 mm.
(a) What is the potential difference between the plates?
(b) What is the kinetic energy of the point charge just before it hits the positive plate, assuming no other forces act on it?
