A particle with a mass of 6.64*10^-27kg and a charge of 3.20*10^-19Cis accelerated from rest through a potential difference of 2.45*10^6V. The particle then enters a uniform 1.60-T magnetic field and the particle's velocity is perpendicular to the magnetic field at all times. The particle then circles inside the magnetic field.
A) using the kinetic energy and electron volt, calculate the velocity of the particle.
B) calculate thr magnitude of the magnetic force exerted on the particle.
C) calculate the radius of the path inside the magnetic field.
