In a region where the magnetic field is B = 10 - 3 T (teslas), a proton (with q = e = 1.6 x 10 - 19 C) moves with a velocity of 1.2 x 107 m/s at an angle of 30o to the magnetic field.
What is the magnetic force on the proton?

 

 F = 9.8 x 10 - 12 N

 F = 1.66 x 10 - 15 N

 F = 1.66 x 10 - 27 N

 F = 9.11 x 10 - 31 N
