2) When a magnetic sector instrument was operated with an accelerating voltage of 3.00x10 V, a field of 0.126T was required to focus the CH4" on the detector. a) What range of filed strengths would be required to scan the mass range between 16and 250, for singly charged ions, if the accelerating voltage is held constant? b) What range of accelerating voltages would be required to scan the mass range between 16 and 250, for singly charged ions, if the field strength is held constant
