A point charge q = 2.5 nC is initially at rest adjacent to the negative plate of a capacitor. The charge per unit area on the plates is 4.5 µC/m 2 and the space among the plates is 6.0 mm.
1. What is the potential dissimilarity among the plates?
___ kV
2. What is the kinetic energy of the point charge just before it hits the positive plate, assuming no other forces act on it?
____µJ
