A mass spectrometer is a device like the one shown in the attached figure. A particle with a total charge q = 4.8⋆10^-19 [C] is directed with a velocity of magnitude v = 4.5⋆10∧6[m/s] in a space where there is a uniform magnetic field of magnitude B = 0.8⋆10^-4 [T] describing a circular orbit of radius r = 1.2 [m]. Determine the mass v m of the particle in kg.

J. J. Thomson is best known for his discoveries about the nature of cathode rays. His other important contribution was the invention, together with one of his students, of the mass spectrometer, a device that measures the ratio of mass m to (positive) charge q of an ion. The spectrometer consists of two regions as shown in the figure. (Figure 1) In the first region an electric field accelerates the ion and in the second the ion follows a circular arc in a magnetic field. The radius of curvature of the arc can be measured and then the m/q ratio can be found. Figure 1 of 1 After being accelerated to a speed of 1.69×105 m/s, the particle enters a uniform magnetic field of strength 0.900 T and travels in a circle of radius 35.0 cm (determined by observing where it hits the screen as shown in the figure). The results of this experiment allow one to find m/q. Find the ratio m/q for this particle. Express your answer numerically in kilograms per coulomb. View Available Hint(s)

A plastic circular loop of radius R and a positive charge q is distributed uniformly around the circumference of the loop. The loop is then rotated around its central axis, perpendicular to the plane of the loop, with angular speed ω. Part A If the loop is in a region where there is a uniform magnetic field B→ directed parallel to the plane of the loop, calculate the magnitude of the magnetic torque on the loop. Express your answer in terms of the variables q, ω, R, and B.

The figure below shows a schematic diagram of a mass spectrometer. A charged particle enters a velocity selector, in which a uniform electric field E (created by charged plates) points to the right, and a magnetic field Bin points into the page. Upon exiting the velocity selector, the particle enters a deflection chamber with a magnetic field B→0,in. The particle travels a semicircular path until it hits a photographic plate at point P: Assume the particle is a singly charged ion with mass m = 2.12×10−26 kg. The magnitude of the electric field is 970 V/m, and the magnitude of both the magnetic field in the velocity selector and in the deflection chamber is 0.900 T. What is the radius r (in m) of the particle's path in the deflection chamber? m
