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 path of radius R using a magnetic field B. If V and B arc kept constant the ratio (("charge on the ion")/("mass of the ion")) will be proportional to

A

R

B

1/R

C

`R^2`

D

`1//R^2`
