Answer

The kinetic energy of the electron is $8.2~keV$

Work Step by Step

In part (a), we found that the energy of the backscattered photon is $~~41.8~keV$ The original energy of the photon was $50.0~keV$ The energy lost by the photon is $8.2~keV$ By conservation of energy, the kinetic energy of the electron is $8.2~keV$
