A particle of charge q = 4.4×10−6 C and mass m = 2.1×10−6 kg moving at some initial velocity v→0 enters a region in which a uniform magnetic field B→ = 0.44 Tj is suddenly switched on. The particle then moves in a helix of radius r = 17 cm and pitch p = 10.7 cm about the y-axis, as shown in the figure. Assuming that the position of the particle when the magnetic field is switched on is (17 cm, 0 cm, 0 cm), express the initial velocity vector using ijk unit vector notation. v→0 = m/s

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)

As shown in the figure, a small particle of charge q = 7.0×10−9 C and mass m = 4×10−12 kg has velocity v0 = 9×103 m/s as it enters a region of uniform magnetic field. The particle is observed to travel in the semicircular path shown, with radius R = 5.0 cm. Calculate the magnitude and direction of the magnetic field in the region.

An ion with a mass m and a magnitude of charge of 1 e is initially at rest when it is accelerated by a potential difference of magnitude ΔV. After exiting the accelerating potential, it enters a region with a uniform magnetic field perpendicular to the ion's velocity. The ion moves in a semicircle of radius R. Next, an ion with a mass m′ and a magnitude of charge of 4e is accelerated by the same potential difference and deflected by the same magnetic field. The radius of its semicircular path is R′ = 3R. Find the ratio of the ion masses, m′/m. m′/m =
