Air Resistance on Electrons

  1. Mar 9, 2013 #1
    Ok so if an electron is launched at a high speed such as 7 million m/s and it travels through air it would encounter resistance that would slow it down even though it is a subatomic particle. Im guessing that you would not be able to apply standard air resistance equations to figure out the force that air resistance would create but is their a way we can calculate this resistance that it would encounter? Basically I need a general resistance for an electron in air. Any help would be appreciated.

    You need to look up the Drude Model. It will require that you find the mean free path of electrons in whatever medium you are using at whatever density. The mean free path of electrons in air should be easily searched for.

    Ok I'll look it up.
