An electron falls from rest through a vertical distance h in a uniform and vertically upward directed electric field
e. the direction of electric field is now reversed, keeping its magnitude the same. a proton is allowed to fall from rest in it through the same vertical distance h. the time of fall of the electron, in comparison to the time of fall of the proton is

Both electron and proton will take the same amount of time,
to fall through distance h.
When the electric field is vertically upwards, and an electron is allowed to fall a distance h, it will accelerate downwards.
When the direction of electric field is reversed, the electron will decelerate in the downward direction.
Since we use a proton with the reversed electric field, it will behave in a manner exactly opposite to that of an electron, in other words, it will accelerate downwards.
Hence electron and proton will accelerate at the same rate.
