A proton travels with a speed of 4.8 ×10^6 m/s at an angle of 56◦ west of north. A magnetic field of 3.4 T points to the north. Find the magnitude of the magnetic force on the proton. (The magnetic force experienced by the proton in the magnetic field isproportional to the component of the proton’svelocity that is perpendicular to the magneticfield.)
