A mass spectrometer is constructed as shown in the image below. The ions of mass m and charge q are accelerated by the voltage U = 100 V and then fly straight to the detector when the forces from the Ē and B fields compensate each other. The B field is 0.5 T. 1. Which forces act on positive ions in a vacuum, moving with the velocity v and simultaneously exposed to an electric field Ē and a magnetic field B (names and formulas)? 2. What magnitude must the field have in order to simply detect positively charged Ar atoms with a mass m = 6.68 × 10-26 kg? 3. What voltage U₂ must be applied to the two horizontal capacitor plates for this purpose if they are at a distance d 1mm from one another and have an area of A 5cm². = = 4. How much charge Q is then on each plate?
