- The accompanied figure shows an arrangement for measuring mass of ions by an instrument called the mass spectrometer. An ion of mass m and charge +q is produced essentially at rest in source S, a chamber in which a gas discharge is taking place. The ion is accelerated by a potential difference and allowed to enter a region of constant magnetic field B q. In the uniform magnetic field region, the ion moves in a semicircular path striking a photographic plate at a distance x from the entry point. Derive a formula for mass m in terms of B0, q, Vacc, and x.A proton has a magnetic field due to its spin. The field is similar to that created by a circular current loop 0.651015m in radius with a current of 1.05104A . Find the maximum torque on a proton in a 2.50-T field. (This is a significant torque on a small particle.)What is the relationship between frequency and angular frequency?
