Answer to Problem 16P
The scattering angle with which the electron gets the greatest energy is
Explanation of Solution
When the scattering angle is
After the head on collision the photon scattered straight back and the kinetic energy gained by the initially stationary electron will be the maximum. The kinetic energy gained by the electron at scattering angle
