Satellite thrusters. The satellites in the SpaceX Starlink constellation use Hall-effect thrusters for orientation adjustments. The full mechanism of the thruster is complicated, but one main feature involves ionizing krypton atoms and then accelerating the freed electronse and the positive krypton ions Kr* before they enter a magnetic field. If they enter a 0.0267 T field perpendicular to the field vector with speed 11.5 km/s, what is the radius of curvature of (a) the electrons (strongly deflected) and (b) the positive ions (barely deflected)? The difference in the deflections separates the electrons and Kr* ions in the small confines of a satellite. The Kr mass is 1.39 × 10-25 kg. (a) Number i (b) Number i Units Units
