The proton is at x= -d and the electron is at x= +d. They are released simultaneously. and the only force that affects their motions is the electrostatic force of attraction that each applies to the other. Which particle reaches the origin first? Why?

There is no fundamental reason for this logic. If you believe this in theory, it is unproven.

The electron will get ther first. They will both have the same force applied to them. So think of F = ma for the proton and electron. The force is the same for both so divide by the mass of the large proton and you get a small acceleration. Divide by the mass of the small electron and you get a large acceleration (remember the force for both is the same). So in the end you see the acceleration of the electron is greater, and since they start at the same position, the one with the larger accelation will cover the same distance faster. Hence the electron
