Magnetic force and radius from magnetic field

  1. Apr 7, 2014 #1
    A magnetic field of 0.0200 T (up) is created in a region

    a)find initial magnetic force on an electron initially moving at 5.00x10^6 m/s (N) in the field

    b) what is the radius of the circular path

    Equations used:
    a) F=qvB
    b) F= kq/r^2

    Thanks in advance
