The mass of the electron is 9.11 x 10-31 kg and the mass of the proton is 1.67 x 10-27kg. Both carry the same elementary charge (positive for the proton and negative for the electron). If I release both particles from rest at the middle point between two charged parallel plates in vacuum, which of the following is true?

Both reach the respectively oppositely charged plate at the same time

The electron strikes the positive plate first

The proton strikes the positive plate first

The electron strikes the negative plate first

The proton strikes the negative plate first

I'm guessing both reach the respectively oppositely charged plate at the same time

    The electron is lighter but has the same force magnitude.
    a = F/m
    so electron accelerates faster.
    It has a negative charge so goes to the positive plate.
