An electron is projected, with an initial speed of  v_{i}=3.10^{5} m s^{-1} , directly towards a proton that is essentially at rest. If the electron is initially a great distance from the proton, at what distance from the proton is its speed instantaneously equal to twice its initial value? Express your answer in meters.
