An alpha particle (m= 6.6 x 10-27 kilogram) is accelerated by a potential difference of 5000 Volt and the enters a region with a vertical (out the page) .75 T magnetic field
a) Determine the speed of the alpha particle.
b) At a certain instance, the alpha particle is moving east. Find the magnitude and direction of the magnetic force on it.
c) Determine the radius of the circular motion.
