A proton and an alpha particle are moving perpendicular to a uniform magnetic field with the same speed. If the velocity of the proton is at an angle of 20° with respect to the magnetic field direction, at what angle to the magnetic field direction would the alpha particle be moving if it experiences the same magnitude acceleration as the proton? The alpha particle has 4 times the mass of the
proton and twice its charge. a. 43° b. 10° c. 62° d. 9.8°
