An electron and a proton start from rest and from the same

Last updated: 7/31/2022

An electron and a proton start from rest and from the same point in a uniform electric field of 360.5 N/C. How far apart are they 3.16 us after they are released? Ignore the attraction between the electron and the proton. Consider the experiment performed with the proton only, then repeat with the electron only. The mass of an electron is 9.109 x 10-31 kg and the fundamental charge is 1.602 x 10-¹⁹ C.
