Question

in a mass spectrometer used for measuring the mass of the ions, the ions are initially accelerated by an electric potential v and then made to describe semicircular path of radius r using magnetic field b. if v and b are kept constant the ratio q/b will be proportional to

Answer 1

Answer and Explanation:

The correct option is (a) 1/R2. Explanation: In mass spectrometer when ions are accelerated through potential V, where m is the mass of ion, q is the charge of the ion.
