Proton and magnetic field question to see if i got the answers right?

  1. Oct 20, 2009 #1
    hey i just need to know if these answers are right i think i got it hopefully

    A proton of mass 1.67 x 10-27 kg is fired with a velocity of 1000 ms-1, into a uniform magnetic field of 2.00 T where the velocity and magnetic field are at right angles.

    (a) What is the magnitude and direction of the force acting on the proton?

    ok so the
    charge of a proton is +1.6x10^-19
    velocity = 1000
    the magnetic feild (B) = 2

    so it would be f=QVxB = 1.6x10^-19x1000x2= 3.2x10^-16
    still dont know how to find the direction of the force any help would be appreciated

    (b) What is the acceleration of the proton?

    To find the direction of the force, use Flemming's left hand rule.
