Calculating the Magnitude of the force

  1. Feb 13, 2014 #1
    1. The problem statement, all variables and given/known data

    Calculate the magnitude of the force on an electron moving at 4×10^6 m/s at an angle of 8 degrees to a magnetic field of 0.3 Tesla. Give your answer in Newtons.
    2. Relevant equations
    the equation that i used was f= qvBsin(8)


    3. The attempt at a solution
    f = 1.602 E-27(4E6)Sin 8
    but i keep getting the wrong answer, what am i doing wrong ,. PLease help me. Thanks

    I just noticed you're not using the right value for q, and make sure your calculator is in degrees mode.
