In 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 the ion")/("mass of the ion"))` will be proportional to:-

A

`1//R^(2)`

B

R

C
