64. The protons are accelerated in a cyclotron in a uniform magnetic field with induction B = 1.2 T. Maximum radius of curvature of the trajectory of the proton is R = 40 cm. Determine: 1) the kinetic energy of the proton at the end of the acceleration; 2) The minimum frequency of the accelerating voltage at which protons are accelerated to an energy of T = 20 MeV.
