Task id17044

In the mass spectrometer, the velocity filter is created by an electric field with a strength of 1.1·102 V/m and a magnetic field perpendicular to it with an induction of 2.0·10-2 T. A deflecting uniform magnetic field perpendicular to the beam has an induction of 9.0·10-2 T. Ions with identical charges and mass numbers 20 and 22 fly through the velocity filter and then rotate 180° in the deflection field (Fig. 28.12). What is the distance between points S1 and S2?
