Question

16. A cyclotron is accelerating deuterons having mass = 2x1.6 x 10-27 kg and charge te. If B=2T, then the required angular frequency of oscillating electric field is: 6 > 10radian/sec (b) 10' radian/sec T T (c) 100 radian/sec (d) 100 radian/sec 17) The maximum radius of the Dees required if deuteron is to acquire 100 MeV of energy in the above question is: (a) 0.5 m b) 1 m (c) 2 m (d) 4 m​
