0A narrow beam of singly charged potassium ions of kinetic energy \( 32 \mathrm{keV} \) is injected into a region of width \( 1.00 \mathrm{~cm} \) having a magnetic field of strength \( 0.500 \mathrm{~T} \) as shown in figure (34-E16). The ions are collected at a screen \( 95.5 \mathrm{~cm} \) 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 \( =A\left(1.6 \times 10^{-27}\right) \mathrm{kg} \) where \( A \) is the mass number.
