Speed of proton vf by time distance between particle doubles

Reference no: EM13647916

A proton and an alpha particle are momentarily at rest at adistance r from each other. They then begin to move apart. Find thespeed of the proton by the time the distance between the proton andthe alpha particle doubles. Both particles are positively charged. The charge and the massof the proton are, respectively, e and m. The charge and the massof the alpha particle are, respectively, 2e =and4m.
Find the speed of the proton Vf(p) by thetime the distance between the particles doubles.
Express your answer in terms of someor all of the quantities e, m, r, and epsilon 0.
