The initial kinetic energies of the protons are equal as their initial velocities are equal. The changes in potential energies, as well as in kinetic energies, of the protons are the same. The final kinetic energy of the proton moving along the path $1212$ is Blankthat of the proton moving along the path $1313.$ Thus, the proton's speed v$2$v$2$ at point $2$ Blankthe proton's speed v$3$v$3$ at point $3.$target $1$ of $2$target $2$ of $2$
