2. A doubly charged calcium ion (4ºCa) is accelerated from rest by a uniform electric field. After moving through a potential difference of 5kV it then enters a magnetic field of a mass spectrometer. It continues moving along a circle of radius 21 cm. What is the kinetic energy of the ion with which it enters the magnetic field? What is the speed of the ion with which it enters the magnetic field? What is the strength of the magnetic field in this mass spectrometer? а. b. С.
