SUMMARY
The kinetic energy of an alpha particle moving from Point A to Point B, where Point A is at +250 V and Point B is at -150 V, is calculated using the potential difference of -400 V. The formula W = -(EPEb - EPEa) indicates that the work done on the particle equals the change in electric potential energy, which converts entirely to kinetic energy. Given that 1 eV equals 1.6 x 10^-19 J, the kinetic energy of the alpha particle upon reaching Point B is 400 eV.
