Problem 6.6

A proton with kinetic energy T=10MeVT=10 \mathrm{MeV} flies past a stationary free electron at a distance b=10b=10 pm. Find the energy acquired by the electron, assuming the proton's trajectory to be rectilinear and the electron to be practically motionless as the proton flies by.

Reveal Answer
Te=mpe4/meb2T=4eVT_{e}=m_{p} e^{4} / m_{e} b^{2} T=4 \mathrm{eV}
