    1. The problem statement, all variables and given/known data

    A electron and proton are far way from each other. They move closer to each other due to their mutual attaction. When they meet is the kinetic energy of the eletron greater, less or even of that of the proton?

    It think it's even, but I'm not sure.

    What remains the same as they approach? Hint: What's conserved?
