A beam of a particles (helium nuclei) is used to treat a tumor located 10.4 cm inside a patient. To penetrate to the tumor, the a particles must be accelerated to a speed of 0.618c, where c is the speed of light. (Ignore relativistic effects.) The mass of an a particle is 4.003 u and its charge is +2e. The cyclotron used to accelerate the beam has radius 1.80 m. What is the magnitude of the magnetic field? The mass of a proton is 1.6605-10-27 kg/u.
