Q/m of a particle in a straight line.

  1. Apr 5, 2009 #1
    What is the value of q/m for a particle that moves in a circle of radius 6.2 mm in a 0.56 T magnetic field if a crossed 220 V/m electric field will make the path straight?



    q/m=2v/(br)^2
    This was given to us in our lab and i plugged everything in and it doesn't turn out right.


    q/m=2(220v/m)/((.56T)(.0062m))^2
    q/m=(440v/m)/.000012055=36499377

    Hi zyphriss2! :smile:

    That formula doesn't look right to me :confused:

    have you tried finding the formula from scratch?
