Two oppositely-charged parallel plates are separated by a distance of 0.03m.
a. What is the strength of the electric field between the two plates if it takes 2.4x10^-19 J of energy to move an electron from one plate to the other.
b. What is the acceleration of that electron as it moves toward the positively-charged plate?
c. If the electron starts at rest, how long does it take to go from one plate to the other?
d. A Proton is launched in between the plates, moving parallel to them. Sketch the path this proton will take.
The Attempt at a Solution
I'm really lost and not sure even what formulas to use except electric field strength but I have joules and I don't know what to do with that.
