Homework Statement
An electron and a proton are separately placed at rest midway between two oppositely charged metal plates. A) Which way will the electron accelerate? B) Which way will the proton accelerate? C) Which particle, if either, will acquire more kinetic energy just before striking a plate? D) What is the ratio of their velocities just before they strike the plates?
Homework Equations
None.
The Attempt at a Solution
I've figured out parts a-c. Not sure about d thought.
a) The electron will accelerate towards the postively charged plate.
b) The proton will accelerate towards the negatively charged plate.
c) Because the charge on either particle is the same, they will acquire the same kinetic energy.
d) How would you solve for the ratio of velocities? Does it have to do with the difference in their masses?
