Homework Statement
How many orders of magnitude smaller is the average drift velocity of a hole than the RMS thermal velocity of an electron moving in free space? (Use the law of equipartition to find the RMS thermal velocity of a free electron.)
This is the last part of the problem, I have already found the drift velocity to be 2.5 x 10-4
Homework Equations
vrms = √3kT/m
This is for an ideal gas, so I'm not sure if it applies.
The Attempt at a Solution
I know I need to find the energy of an electron, but I can't seem to find anything about how to calculate that in a vacuum, just how to find it based on pressure and temperature.
