Can anyone explain to me why electric field lines never cross?

A free electron and a free proton are placed in an identical electric field. compare the electric forces on each particle. compare their accelerations. How do I do this? i know that the electron will move in the same direction of the fields while the proton move opposite way. I think that the electric forces are the same in magnitude and opposite directions for the charges. The acceleration of the electron is greater than the proton because it moves in the same direction as the field. That's what I think. Can anyone give me some comments?

Have you considered the relative mass of the electron and proton and how that affects the acceleration?

The mass of the proton is greater than the electron, so the proton should move faster?

"The mass of the proton is greater than electron, so the electron accelerate faster?"

If the mass of your car is greater, should your car accelerate faster?
