Homework Help: Proton Speed In X,Y,Z Plane

  1. Mar 15, 2010 #1
    Proton's Velocity

    1. The problem statement, all variables and given/known data

    What is the speed of the proton?

    2. Relevant equations

    3. The attempt at a solution

    I rearranged the equation so that I solve for velocity, v. I determined that r^2 is 1.8*10^-5 m. I plugged in 1.1*10^-3 for B. The q for the proton is 1.6*10^-19.

    Plugging all that and the constants in gave me a velocity of 1.2*10^8 m/s.

    Oh yeah, do you guys know the specific right hand rule for this situation? I need to use it to figure out the direction of this proton.
