As shown, an electron (charge -e, mass me) moving with an initial velocity in the positive y direction, enters a region (indicated by the shaded area) of uniform magnetic field, of magnitude B. The electron follows a semi-circle path and then leaves out the magnetic field's region at x = -D. The kinetic energy of the electron at x = -D is:

As shown, an electron (charge -e, mass me) moving with an initial velocity in the positive y direction, enters a region (indicated by the shaded area) of uniform magnetic field, of magnitude B. The electron follows a semi-circle path and then leaves out the magnetic field's region at x = -D. The kinetic energy of the electron at x = -D is: O e?BD² / 8me O eBD| 2me O 2e?B²D² / me o e?BD² | 2me eBD | me
