Question

Problem: In a mass spectrometer, a singly charged ion having a particular velocity is selected by using a magnetic field of 0.12T perpendicular to an electric field of 1.5×10³ V/m. A magnetic field of this same magnitude is then used to deflect the ion, which moves in a circular path with a radius of 1.2 cm.

Part A: What is the mass of the ion?

Explain each step in detail.
