U pulaDUlic path a mass spectrometer used for measuring the masses of ions, the ions are initially accelerated by an electric potential V and then made to describe semicircular paths of radius R using a magnetic field B. If V and B are kept constant, the ratio charge on theion | mass of theion will be proportional to [AIPMT (Prelims)-2007] (1) R (2) (4) R2
