Question: A narrow beam of singly-charged potassium ions of kinetic energy 32 keV is injected into a region of width 1.00 cm having a magnetic field of strength 0"500 T as shown in figure (34-E16). The ions are collected at a screen 95"5 cm away from the field region. If the beam contains isotopes of atomic weights 39 and 41, find the separation between the points where these isotopes strike the screen. Take the mass of a potassium ion - A (1"6 x 10-27) g where A is the mass number.
