A photon of wavelength

0.050\,\text{nm}

collides with a free electron that is initially at rest. After the interaction, the photon is observed to travel at an angle of

60^{\circ}

relative to its original direction. Using

h=6.63\times10^{-34}\,\text{J}\cdot\text{s}

m_e=9.11\times10^{-31}\,\text{kg}

, and

c=3.00\times10^{8}\,\text{m/s}

, calculate the magnitude of the electron’s momentum immediately after the collision.
