An electron and a proton are released simultaneously from rest and start moving toward each other due to their electrostatic attraction, with no other forces present.
Which of the following statements are true just before they are about to collide? (There could be more than one correct choice.) A) They are closer to the to the initial position of the electron that to the initial position of the proton.
B) They are closer to the to the initial position of the proton that to the initial position of the electron.
C) They are at the midpoint of their initial separation.
D) They both have the same speed.
E) The electrostatic force exerted on the proton is greater than the electrostatic force exerted on the electron.
