A proton enters the gap between a pair of metal plates (an electrostatic separator) that produces a uniform, vertical electric field between them. Ignore the effect of gravity on the proton.
(a) Assuming that the length of the plates is 15.1 cm, and that the proton will approach the plates at a speed of 13.8 km/s, what electric field strength should the plates be designed to provide, if the proton must be deflected vertically by 1.45 x 10-3 rad?
