In a mass spectrometer,a variety of singly ionized atomic nuclei are directed into a magnetic field where they are deflected and strike a detecting screen.The particles to undergo the greatest deflection are the particles with the
A)least mass.
B)greatest mass.
C)same for all

Question

Quizplus · Accepted Answer

The deflection of a particle in a magnetic field is directly proportional to its charge and velocity, and inversely proportional to its mass. Since all particles in the mass spectrometer are singly ionized, they have the same charge. Therefore, the particles that will undergo the greatest deflection are those with the least mass.
