A proton is accelerated initially by applying a potential difference of 10 V in a small area. After the electron leaves the potential difference with a speed v0, it travels between two charged plates with distance of 0.6 cm between them. The plates have a potential difference of ∆V = 50 V across them, with the top plate being high potential. Inside the plates the proton is deflected by amount ∆y.
a) What is the initial speed v0 of the proton after leaving the potential difference
b) What is the magnitude and direction of the electric field inside the plates
c) What is the charge density, σ, of the plates?
d) If each plate is 3 cm long, by how much ∆y will the proton be deflected in the vertical direction after coming out of the plates?
