You are working in a biotechnology company that specializes inthe design of mass spectrometers with the team that develops thevelocity selector. As part of the project design, you are in chargeto solve the following problem. Molecules of mass 124u (u =1.661×10−27 kg), have been ionized knocking out one electron, soits charge is ? = +?. The molecules, travelling horizontally, areaccelerated until they reach a speed ?0 = 4.80 × 104 m/s, and thenpass through a region between two horizontal electrode plates 2.50cm long, separated a distance 2.00 cm. There is a vertical electricfield of magnitude E pointing upwards, between the plates. Afterthe molecules clear the region between the plates, they travel ahorizontal distance ? = 1.50 cm (there is no electric field in thisregion) and must impact on a detector at vertical distance ℎ = 8.10mm above the location they entered the plates (that is, thevertical displacement, from the time the molecules enter the regionbetween the deflecting plates, until they hit the detector, is 8.10mm). You must find the magnitude E of the electric field, toproduce this result.
Make sure to:
• Draw a picture
• Include sufficient work.
• List any assumptions that may simplify the problem.
