Triply charged uranium-235 and uranium-238 ions are being separated in a mass spectrometer. (The much rarer uranium-235 is used as reactor fuel.) The masses of the ions are 3.90 ✕ 10−25 kg and 3.95 ✕ 10−25 kg, respectively, and they travel at 9.00 ✕ 105 m/s in a 0.323 T field. What is the separation (in m) between their paths when they hit a target after traversing a semicircle?

A small cart (which you may treat as a point charge) carrying a charge of 3.000 C moves along a straight track at a constant speed of 12.000 m/s. What is the magnitude of the magnetic field at a point beside the track that is 13.000 cm away from the track and 24.000 cm farther down the track than the charged cart? μΤ

A charged particle moves into a region of uniform magnetic field, goes through half a circle, and then exits that region. The particle is either a proton or an electron (you must decide which). It spends 130 ns in the region. What is the magnitude of B? Give your answer in T. (mproton=1.672x1027 kg, melectron-9.1lx10-3! kg, e-1.602x10-19 C) OB

Starting from rest, an electron is accelerated through a region between two oppositely charged plates, as shown in Figure 1. The distance between the plates is 10 cm and the magnitude of the potential difference between them is 100 V. Immediately after exiting the region with the uniform electric field, the electron enters a region with a uniform magnetic field of 0.85 T, directed into the page. (a) Calculate the magnitude of the electric force on the electron. (b) Calculate the work done by the electric force on the electron. (c) Determine the electron's speed when it enters the magnetic field. (d) Determine the magnitude and direction of the magnetic force on the electron when it enters the magnetic field. (e) Suppose that the experiment was repeated with the locations of the positive and negative plates switched, and the electron was replaced with a proton, but nothing else was changed. Calculate R,/R., the ratio of the radius of the proton's path in the magnetic field (R,) to that…

An electron moves at a speed of 810 m/s perpendicular to the direction of a uniform magnetic field of 0.4 T. What is the radius of the electron's circular orbit in units of nanometers (1 m = 10° nm)? (in units of nanometers)

Aircraft sometimes acquire small static charges. Suppose a supersonic jet has a 0.35 μC charge and flies due west at a speed of 640 m/s over the Earth’s south magnetic pole, where the 8.00 × 10-5 T magnetic field points straight up. v = 640 m/sq = 0.35 μC What is the magnitude of the magnetic force on the plane, in newtons?
