Kinetic Energy

  1. May 7, 2009 #1
    1. The problem statement, all variables and given/known data

    Suppose that I want to compare the Kinetic Energy of an electron to the Kinetic Energy of an alpha particle if they both have the same radius of curvature in a magnetic field.

    2. Relevant equations

    qvB = mv^2/r
    KE = 1/2 mv^2

    3. The attempt at a solution

    I am studying for my PE and I have run across this problem. I just want to know if the equations that I show are the correct ones for this problem. I am wondering if I have to set two (2) versions of these equations equal to each other (one for electron -- one for a-particle) ??

    If anyone has a solution then please share it with me.

    Have you tried working the problem all the way through? It shouldn't be hard...
