Particle with a mass of 6.64 x 10^-27 kg and a charge of +3.2 x 10^-19 C is accelerated from rest through a potential difference of 2.45 x 10^6 V. The particle then enters a uniform 1.6 T magnetic field. If the particle's velocity is perpendicular to the magnetic field at all times, what is the magnitude if the magnetic force exerted on the particle?
