Question 8 0 l 1 point A proton enters a parallel plate system moving with an initial velocity of 11208.1 mfs perpendicular to the electric field. The proton enters at the the positive plate and the electric field between the plates moves it in the direction of the negative plate. The plate separation distance is 18.5 cm and the potential difference between the plates is 6.9. What is the magnitude of the final velocity of the proton when it hits the negative plate?
