Expert Solution

Magnitude of Momentum of electron after collision = (as angle is 180^o )

= 6.62x10^-34/1.556x10^-11

=4.254x10^-23 kgm ----------------------------------------(1)

Eenergy of incoming photon E=

=

=118.5610^-15 J

Kinetic energy of electron KE =p²/2m ( where p is mometum of electron and m mass )

=

=0.994 x10^-15 J (ANS)
