Q. A pair of oppositely charged parallel plates are separated by a distance of 5.0 cm with a potential difference of 550 V between the plates. A proton is released from rest at the positive plate at the same time that an electron is released from rest at the negative plate. Disregard any interaction between the proton and electron.a) How long does it take for the paths of the proton and the electron to cross?b) How fast will each particle be going when their paths cross?c) How much time will elapse before the proton reaches the opposite plate?
